If that's all you pay for water supply and discharge then you are living in a great area. Now we will put together the battery power components. Adjust the Shower Valve. Next, I placed my Arduino Nano in the middle of the board and marked where the header pins went through. Right now, the only indication that the device needs to be recharged is when the battery manager board cuts off the power. Once easily installed, this unique thermometer displays the current temperature of the water flowing through your showerhead on a rotatable waterproof LED screen and is able to generate its own power from the flow of the water - no batteries required. How you choose to mount the device depends on the layout of your shower. RP19804. This is the current RP19804 cartridge that began shipping in 2015. The device works, but the values are wrong - make sure the flow sensor you're using has the same conversion factor of 450 pulses per litre. My solution was to create a rectangular cutout in the lid, and glue in a piece of transparent plastic from some vegetable packaging. Use an electric appliance in the bathroom), Question Since I recently got my own 3D printer, I decided to go with the first option. Some of these ideas are bordering on feature creep, which is why I didn't develop the software any further. On the outside of the sensor is a small compartment which contains a small PCB with two components: a resistor, and a hall-effect sensor. It would be a lot easier to reduce my water consumption if I actually knew how many litres I was using each time! I soldered one wire to the ground rail, and the other to digital pin 3. At my local hardware store, there were 1/2" couplings in brass, iron, and PVC. I did a bit of research, and found that different shower heads can use anywhere from 9.5 litres (2.5 gallons) per minute to less than 6 litres (1.6 gallons) per minute, if you have a flow restrictor installed. (Only because I don't know how to do it your way, but someday I will. Of course, I am assuming your shower uses a 1/2" NPS thread, as mine did. Installation typically takes less than 15 minutes. The Streamlabs Water Monitor will easily pay for itself by alerting you to a running toilet, dripping faucet/shower or leaking hose Bibb/water heater. Of course, if you're using an enclosure with a transparent lid, this isn't needed at all. An 18650 cell would work, but it won't fit in my custom enclosure so you'll need to design your own, or use an off-the-shelf enclosure. Set the valve's adjustable rotational limit stop to prevent the temperature handle from being turned to dangerously hot levels. I let the glue sit for 12 hours to make sure it was completely dry. The flow sensor jack is on the side, but when the flow sensor is plugged in, the plug blocks water from entering the jack. This will only work if you're using an off-the-shelf enclosure which has a smooth backing, or you printed my custom enclosure on a printer with a glass build plate. To test, turn the shower on (both hot and cold) and carefully monitor leaking water under the shower. Any single-cell Li-Ion or LiPo battery will work, so long as it fits into your enclosure. Since it will reside in a shower, it must be able to survive extreme humidity and the occasional splash. Once the hot water stop … This causes the water to back up and come out the shower head. I recommend always plugging in the 3.5mm plug before the USB plug, as the process of plugging in the cable could cause the plug to short across the metal receptacle. The ESP microcontrollers are compatible with the Arduino IDE so they're pretty straightforward to work with. Save Water & Money With the Shower Water Monitor Step 1: Waterproofing. You could have the ESP send an email when the water quota is exceeded, or you could have them constantly logging the water usage to a database (SQL if you have a domain already). You could buy a USB cable assembly with a USB A connector on one end and tinned wires on the other end, but if you're like me, you probably have a dozen random USB cables lying around that you don't need. Once you've seen the flowchart, take a look at the attached Arduino code. Then I soldered two more header pins connected to pins A4 and A5 on the Arduino. Test Your Shower Head's Flow. Since the walls are so thin, reducing the infill percentage doesn't really change the total print time or total material, so I just kept it at 100%. Replace the hot water stop in the faucet while the water continues to flow. I decided to use this sick-looking chrome button on the front panel. adjust moen shower valve for hot water tatoo writing sex from delta monitor shower faucet temperature adjustment how to adjust a shower valve water temperature from delta monitor shower faucet temperature adjustment. During that time, the device records all of your heartbeats.A Holter monitor test is usually performed after a traditional test to check your heart rhythm (electrocardiogram), especially if the electrocardiogram doesn't give your doctor enough information about your heart's condi… Both the 709CNH and the 1029CNH are IP65 rated for dust and splashing liquid, whereas the 1029GNH is IP67 rated for dust and complete waterproofing. Install a pressure balance tub and shower valve, such as those found in the broad selection of the Delta® Monitor® series. For example, I'll add a few temperature sensors to know the water temperature, and in the future add some valves to make it always the right temperature. This will allow us to use any generic mobile device charger (such as an iPhone charger) to charge this device. I chose to use digital pins 2 and 3 for the button and flow sensor because they are hardware interrupt pins. The standoffs each have a male thread on one end and a female thread on the other. Single-function valve must be adjusted for each shower. Most importantly is the cost per litre. The flow sensor comes with a 3-pin JST-XH connector. The most difficult aspect of this project is making the whole thing waterproof. ( so i have to solder on pin 4-6 on the left side and the 2, 4, 7 & 8 pin on the right side of the ESP?) See this tutorial for an example of blinking an LED without using the delay() function. A shower diverter valve enables you to control the amount of water that goes into separate outlets on the shower head. That way, the accuracy doesn't matter, only the precision (which is 1/450 L ≈ 2.2 mL since it sends 450 pulses per litre) and repeatability. If you are doing something that takes longer than just blinking an LED, such as updating an LCD screen, the time it takes is not negligible, and after a few cycles it will add up. I also used 100% infill. That's 30 gallons of water down the drain. The problem could just be an old, faulty shower lever, in which case you should try replacing it. They also have a built in WiFi adapter. Did you make this project? They're supposed to be waterproof, and they come with a rubber ring to prevent moisture from entering the enclosure through the threads. These features would all require the use of EEPROM - the Arduino's built-in non-volatile memory. After viewing product detail pages, look here to find an easy way to navigate back to pages you are interested in. If possible, I recommend using a salvaged battery (like I did) because shipping batteries is often expensive! I didn't factor in the flat rate monthly service charges for metering; I only used the cost per cubic metre. Next, solder a wire from the positive output of the charger (located beside the positive battery wire) to the positive input on the boost converter. Remove the center cap from the shower handle if one is present using a slotted screwdriver. Question High Precision Monitor: built-in high precision temperature sensor, providing 0~100°C measurement range and ±0.5°C accuracy. Insert the button through the hole in the lid, and tighten the nut from the back side. I'm new to this whole DIY electronic stuff and I want to make this for a personal project, but I want to add a wifi shield to connect to an app that I'll develop, and add a temperature sensor, but I have no clue how to integrate these two with your circuit. Thank you for the suggestion :), i have another question, since i'm not familiar with Ardiuno Nano, ESP32 AND ESP8266, do i have to change the wiring? Pro-Tip: Place the part in front of a small fan while the glue is drying. If you wanted more precision, you could use a different flow meter. Won't the audio jacks allow water to get into your enclosure (or did I miss something)? There can be one of several reasons for this: The valve could be upside down; The length from the valve to the tub spout is outside of the 8" to 18" rule If you want, you can solder a JST RCY connector to the battery and charger for convenience (I did this), but it is not necessary. Since our Arduino, LCD screen, and flow sensor all need 5V, we must set the output of the boost converter to 5V. As in are the pins in Arduino Nano ( you solder on pin 4-6 on the left side and the 2, 4, 7 & 8 pin on the right side of the arduino nano) the same as the ESP32/ ESP8266? This has the tendency of making the … I got this package of standoffs which has the 10mm ones to mount the LCD, and longer ones to hold the lid to the base.

The Streamlabs Water Monitor is the ultimate solution for tracking your water consumption and providing real time alerts to possible leaks. The row of 16 header pins on the LCD should be on the top - make sure you don't mount the LCD upside down! I was recently thinking about this question, and I realized that I don't actually know how much water is used when I shower. Then we execute whatever additional steps we want. Some showers might have a ledge close enough to the shower head that you could simply place the device there. I'm trying to do absolutely the same as you, integrate with wifi and add a temperature sensor, but I really don't know how. I used an old 12V fan from a computer power supply. My Delta Monitor shower and tub faucet has very low water output/pressure. About 75% of the total time spent on this project was figuring this part out. Connect the "Vcc" pin to +5V, the "Gnd" pin to ground, the "SCL" pin to A5, and the "SDA" pin to A4. In this Instructable, I'll explain how I built this. Next, solder the 3.5mm audio cable to the pads. Well, you could calibrate it using a known volume of water or whatever liquid you're planning to use it on. Also, I've found that these connectors are sealed pretty well so even if water did enter the jack, it would make its way into the enclosure. Be sure to observe the correct polarity as indicated by the markings on the charger board, as the board is not protected against reverse battery polarity!

The last part to solder is the flow sensor. With a timer it will be a great tool ! The green and white are for data transfer, and can be ignored. I put the male thread through the holes in the LCD and tightened an M3 nut to each one. There's a problem loading this menu right now. How good (accurate) is that flow sensor? I used this one from Banggood. Rather than buying a USB cable assembly, I just got a micro USB to USB A cable that I didn't need and snipped the micro USB connector off. Dealing with a “fussy” shower faucet is a bad way to start your day. I've included a complete wiring diagram, which you can follow, or see my written steps below if you prefer a more guided approach. The lid has a 16mm hole for the momentary pushbutton, and a rectangular cutout for the screen, as well as the four mounting holes to hold the screen in place. The average shower uses 10 gallons of water, a dishwasher uses about 6 gallons, and clothes washers use about 7 gallons of water, according to the Department of Energy. Next, desolder the three wires by heating them up with a soldering iron and lifting them off, one at a time. At one point on the propeller is a magnet. 1 year ago, I actually live fairly close to you then, in Burlington. Anti-scald shower valves — also called thermostatic valves — help you keep the temperature consistent so that you don't have to constantly fiddle with the taps or risk getting shocked by a burst of hot or cold water. Finally, screw the shower head onto the end of the flow sensor. Reply This would allow the data to be retained even after the device is turned off. The design is surprisingly simple and ingenious. This cool new Shower Thermometer is a handy way to monitor the temperature of your shower or bath in real time. Just saw your project and I'm totally amazed by it. Xenarc Technology manufactures a tough, dependable array of weatherproof and waterproof LCD monitors that work equally well, whether indoors or outdoors. Therefore, I was forced to create a custom character. It's also the only shower head to do all this with a water powered turbine that generates power with the flow of water, no batteries necessary! How would you go about this ? on Introduction. 1 year ago. It's always good to make use of parts you have lying around. The following byte array is used to represent this symbol: After creating this array, the special character must "created" and stored. The benefit of using this method over the simple delay() function is that delay() puts a gap of time in between the instructions, but doesn't account for the time it takes to execute the other instructions in the loop() function. The package of standoffs I bought doesn't include any that are that long, but it does come with 20mm and 10mm ones that can be attached together. I have taken out the cartridge several times and blown out the line with air, but it does not help. This will make it much easier to write the code. More information on this is here. I really like your instructable, but I have used somewhat easier and much simple approach to the same problem. For this point onward, when I refer to the enclosure, I am talking about my 3D printed one. Unfortunately 3D printing with transparent filament is still in its infancy, so we'll have to get a bit creative. Be sure to tighten these securely, but not too tight or you risk breaking the plastic enclosure. I soldered these onto the perfboard where I previously marked. The charging jack (which is normally unplugged during use) is on the bottom, so water will not flow up into it. Usually spinach or other leafy vegetables come in large clear plastic containers. Next, I stripped the white jacket off the cable to reveal only two wires inside: a red and a black wire. The email approach would be simple, but wouldn't let you access as much data. Of course, you don't have to follow my steps exactly! If it is, the first thing we do is set previousMillis equal to the current time. I used a 3.5mm headphone jack for this. In my area we have a fixed rate per metre of water regardless of how much we use, the sewage cost per metre is much more than the cost to purchase the water. I squirted a line of superglue around the perimeter of the cutout, and then placed the clear plastic on. This includes the battery, master switch, battery monitoring/charging board, and the boost converter. I ordered this 3.5mm audio plug cable assembly from Digikey. Since we soldered headers, we just need four female-to-female jumpers. Once this is done, to print the custom character we use the following line: The LCD can have up to 8 custom characters. Celsius/ Fahrenheit display selectable. Were you able to do this? The battery I used is a 3.7V 1500 mAh single-cell lithium ion battery. I think the easiest way to accomplish what you're describing would be to replace the Arduino Nano that I used with an ESP32 or ESP8266. Inside you will find a screw that secures the handle to the valve stem. The particular one I used was pulled from a broken Playstation controller. )I have been using a big tub, which I have used to collect the water and then after my bath or during, have poured the water in buckets and used it for the toilet. I know when I'm in the shower sometimes my mind wanders, thinking about a cool new projects idea or trying to decide what to have for breakfast, while water is just gushing down the drain. Since the total will be zero by default, the button won't appear to do anything yet. I have factored in the supply and sewage charge I have to pay. First plug in the 3.5mm connector from the flow sensor. I was thinking of using something similar for beer brewing :). Then you could see what times of the year people have more frequent and longer showers. If this isn't the case, you will need to get extra adapters. One way to test if the shower valve or the tankless heater is the source of the erratic behavior is to set the lavatory faucet to run a medium low level of hot water and see if this affects the delivery of hot water from the shower. To read the sensor, we apply +5V to the red wire, negative to the black wire, and read the digital signal from the yellow wire. There are a few parts in the code you might want to change. If you accidentally plug the charger into the sensor port, or vice versa, there won't be any damage to the device. 1 year ago At first, the signal is constantly zero volts. If you're updating the LCD screen on a clock, it would quickly become inaccurate and fall behind. It seems to have good supply side pressure. The mixture of hot water and cold water available in a shower or tub can be adjusted at the shower valve stem, the part found under the faucet. A very old shower could use even more water. Let it run for about a minute. (Of course I can't reuse all the water but a significant amount can be used again. I used more double-sided tape to secure the battery to the bottom of the enclosure beneath the LCD screen. Using its innovative ShowerStart technology, the shower head monitors water temperature and cuts the flow to a trickle when it’s reached a comfortable 95 degrees. This step is pretty straightforward. The flow sensor has an arrow to indicate the intended direction of flow. Zoe+Ruth Non Contact Forehead and Ear Thermometer, Medical Grade Fast Accurate, Digital Infrared for Instant Temporal Fever Temperature for Baby, Kids & Adult. Since the screen shouldn't be exposed to moisture, we're stuck with the second option. Did you take a shower this morning? What exactly would you be using it for? However, the one you linked to appears to use the same 4.5 factor, which suggests it's just the same flow meter that I used, in a different enclosure. Be sure the nuts are very tight so that when you tighten the screws, the standoffs don't turn. Color of LED lights changes automatically according to water temperature, Digital LCD Waterproof Timer Shower Clock New Design Bathroom Clock Wall Mounted, Suction Cup, Displays Time, Temperature, and Indoor Relative Humidity (WHITE), URHEALTH PC828 Infrared Thermometer | Digital Thermometer for Kids and Adults, Child and Baby Thermometer | No Touch Medical Forehead Thermometer | Instant Results Touchless Thermometer for Humans, FIRHEALTH Wall Mounted Thermometer, Non-Contact Wall Mounted Forehead Thermometer for Adults and Kids, LCD Digital Display Fever Alarm Thermometer, ELLO&ALLO LED Rainfall Waterfall Shower Head Rain Massage System with Body Jets Stainless Steel Bathroom Shower Panel Tower System, Brushed Nickelâ¦. The exact process for adjusting the hot and cold water will depend on the type of faucet in your shower or tub, but the general idea is as follows: Remove the handle. In my shower, I have a basket attached with suction cups that I placed the device inside of. Adjusting the shower temperature control valve can save you from an occasional burn if your elbow should push the single lever up by accident and the hot water showers on you instead. Our products are designed to be easy to install and use. Comes with all Delta pressure balance tub and shower faucets May need to be manually adjusted for seasonal ground water temperature changes If you connect a multimeter to the output of the boost converter and turn on the master switch, a voltage should be displayed. I've used them in previous projects and I really like the way they look. The Power to Monitor, Control & Conserve Water in the Home. Top subscription boxes â right to your door, Â© 1996-2020, Amazon.com, Inc. or its affiliates. First, I inserted the connector into the bottom-most hole in the enclosure. I soldered the other end of the "sleeve" wire to the negative input on the charger, beside the micro USB port. This will allow us to remove the Arduino for programming. The pinout of the connector is shown in one of my annotated images. I do not know where you live but I live near the Great Lakes, Niagara Region ,Ontario, the largest fresh water supply in the world. 1 year ago. I recommend doing this before the device is turned on, because it's possible for the plug to make unwanted connection as it's being inserted. If you don't have access to a 3D printer, here are some off-the-shelf enclosures I've found that claim to be waterproof, and would probably work. Finally, solder a wire from the switch's normally-open pin to the boost converter's negative input. I added a bit more superglue around the edge after just to make sure it was sealed. Please note I have not purchased either of these enclosures so I make no guarantees that all the components will fit inside! I don't recommend trying to use an old headphone cord, as those tend to have very thin enamelled wire, which is nearly impossible to solder. I decided to design and build a device that would display the total volume of water used per shower, the cost of the water, and the flow rate. Shower Water Monitor Tracks The Dollars And Cents. A voltage divider wouldn't even be needed since the battery voltage is always less than 5V. Then I wrapped some electrical tape around the exposed metal on the two 3.5mm jacks, just to ensure nothing gets shorted by contacting the connectors. Carefully test the tub/shower water … Now we can fit all the electronics inside. This configuration has +5V on the tip, signal on the ring, and ground on the sleeve. This is the same configuration used for the charging port, from step 6. 6 weeks ago Before using it, I decided to investigate how it works. I had to trim the corners a bit so that the screws would fit. It isn't held in with any glue, it's just kept in place with the plastic lid. All delta single lever shower faucets are similar. Very nice idea. Plus, there are M3 screws and nuts, so you don't need to buy any additional hardware. Baby Shower Gifts. This is not ideal because the wires are too short, and the connector has exposed contacts which can easily be shorted by stray water droplets. When the flow starts, the frequency of pulses quickly comes up to speed and reaches a steady state. I have commented almost every line to make it clear what each line is doing. While there's no water running, the front panel button shouldn't do anything besides clearing the total and clearing the screen. This one fits my criteria and seem to need the same coef so would I be able to use this one instead without any modification ? Now also helping to raise water consumption awareness is Hydrao, a smart shower head. As superglue dries, it tends to leave a vile white residue behind, which we certainly don't want on our transparent window. Our cutoff valves use microchip technology to control the amount of time spent in the shower, as well as preventing immediate restarting. The most difficult aspect of this project is making the whole thing waterproof. You can download the STL files from my Thingiverse page. Response must be less that 100,000 characters. Simply remove these screws, and pull out the circuit board. This type of battery tends to be very thin and flat, so you could probably use one twice as big as mine without any problems. The rotational … Step 2: My Custom 3D Printed Enclosure!. Grasp the rotational stop dial in the center of the faucet with a thumb and forefinger. To ensure the shower valve is in fact a Delta Monitor, look on the trim plate, there should be the words Delta on the bottom and Monitor on the top (see pictures). One touch to the right and you’re blasted with cold water. Turn on the shower to full capacity. As a precaution, direct the water into the drain only since you’ve tested this already and not at any walls or shower doors. This revealed a short bit of pipe protruding from the wall, with 1/2" NPS male threading. In order for the LCD screen to fit in the enclosure, we'll need to bend the header pins backwards. I want the program to have the following features: The program follows a simple structure. After that, I cut two wires and connected them to the terminals of the pushbutton. Once the shower stops, pressing the front panel button will reset the measurements and clear the screen. Every time the magnet passes by the hall-effect sensor, it toggles between high and low. Also, make sure you don't over-tighten the screws, or the plastic lid could deform and not seal properly. A Holter monitor is a small, wearable device that keeps track of your heart rhythm. Locate the following line, and change that value to match the cost where you live: If you prefer to use gallons over litres, change all the "LCD.print()" lines that refer to "L" or "L/s" to "G" or "G/s". Solder the red wire from the USB cable to the middle tab (which is the tip of the connector) and the black wire to the long sleeve tab. Then I inserted the jack through the enclosure and secured it in place with a nut.
