- thank you in advance and sorry for bad english, Reply Adjust the Shower Valve. In my case, I used the packaging from a "pepper medley". 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". These features would all require the use of EEPROM - the Arduino's built-in non-volatile memory. You can download the STL files from my Thingiverse page. Conveniently, our flow sensor has the exact same thread size! Xenarc Technologies was the first to bring IP65, IP66 , IP67 and IP67K dust/water proof capacitive touchscreen monitor displays to the market. Since the screen shouldn't be exposed to moisture, we're stuck with the second option. Then I inserted the jack through the enclosure and secured it in place with a nut. The flow sensor comes with a 3-pin JST-XH connector. It can be printed without any rafts or supports, but I used supports just to be safe. 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. 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. I didn't factor in the flat rate monthly service charges for metering; I only used the cost per cubic metre. Can i have your opinion on how to connect the shower monitor to the phone? This causes the water to back up and come out the shower head. 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. 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. This is achieved by turning the knob on the potentiometer with a small screwdriver. Turn on the shower to full capacity. I have commented almost every line to make it clear what each line is doing. 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. (Of course I can't reuse all the water but a significant amount can be used again. The standoffs each have a male thread on one end and a female thread on the other. To make the screen visible, it could either protrude through a cutout in the lid of the enclosure, or be placed behind a transparent window. This will provide power to the Arduino, the LCD, and the flow sensor. The USB port on the charger will not be used, because it would be difficult to make the USB port penetrate the enclosure without allowing moisture in. About 75% of the total time spent on this project was figuring this part out. A Holter monitor is a small, wearable device that keeps track of your heart rhythm. The four holes on the corners of the box are to hold the lid on with 30mm standoffs. Now it's time to solder everything together! The battery I used is a 3.7V 1500 mAh single-cell lithium ion battery. The PVC one was the cheapest, so I got that one. Then I used four M3 screws to secure the female ends of the standoffs through the lid of the enclosure. Smart 5 in 1 Modes + Storage Case. Shower water pressure and temperature can be affected whenever water is turned on elsewhere in the home. This will allow us to use any generic mobile device charger (such as an iPhone charger) to charge this device. With a ShowerBoss® you are able to program and monitor the amount of water used during every shower. Set the valve's adjustable rotational limit stop to prevent the temperature handle from being turned to dangerously hot levels. Screen is blank with backlight off - check that the power LED on the Arduino is on, and check that the screen has power, Screen turns on briefly, then everything stops - you probably set the voltage from the boost converter too high (the components can't handle more than 5V). First, I cut some male header pins and soldered them onto the perfboard on the +5V and ground rails. First, I removed the shower head. 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! This would allow the data to be retained even after the device is turned off. The WaterHawk is the only showerhead on the market that displays real-time water usage and temperature data as well as a color coded quick indicator LED ring to let you know precisely when the water temperature is up to your liking, avoiding wasted water. Since I recently got my own 3D printer, I decided to go with the first option. Another useful feature would be a battery indicator. This is the same configuration used for the charging port, from step 6. https://www.banggood.com/G1-14-1_25-Water-Flow-Hal... On the first line, display a rapidly-updating count of the total litres, On the second line, display the total cost of the water, When the shower is running, the pushbutton toggles between showing the cost or the flow rate, The sensor should be read using an interrupt routine to avoid gross polling methods, When updating the screen, we should only update the values that have changed, rather than overwriting the entire screen each time (this would cause noticeable flicker). Finally, solder a wire from the switch's normally-open pin to the boost converter's negative input. 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. The pinout of the connector is shown in one of my annotated images. Your recently viewed items and featured recommendations, Select the department you want to search in, All customers get FREE Shipping on orders over $25 shipped by Amazon, Mothermed bath thermometers care your lovely baby, Price and other details may vary based on size and color. At one point on the propeller is a magnet. If you press the front panel button, the flow rate will be displayed on the bottom line. 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. A very old shower could use even more water. My solution was to create a rectangular cutout in the lid, and glue in a piece of transparent plastic from some vegetable packaging. Your doctor may want you to wear a Holter monitor for one to two days. Some showers might have a ledge close enough to the shower head that you could simply place the device there. 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). Waterproofing. Since we already attached a 3.5mm plug to the sensor, we just need to solder a 3.5mm female jack. Inside you will find a screw that secures the handle to the valve stem. See this tutorial for an example of blinking an LED without using the delay() function. Step 2: My Custom 3D Printed Enclosure!. It's time to stuff all the electronics into the enclosure and hope the lid closes. Insert the button through the hole in the lid, and tighten the nut from the back side. Unfortunately 3D printing with transparent filament is still in its infancy, so we'll have to get a bit creative. I let the glue sit for 12 hours to make sure it was completely dry. Next, solder the 3.5mm audio cable to the pads. Let it run for about a minute. 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. It isn't held in with any glue, it's just kept in place with the plastic lid. See how much your family can save in a year with the Shower Manager. I've used them in previous projects and I really like the way they look. Rather than explaining every single line of code here, I suggest you first read over the attached flowchart, which gives a high-level overview of what the program does. 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. Because of the risk of scalding and energy that is wasted because water is kept at such a high temperature, it's a good idea to adjust the shower temperature control valve. 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 ? Most importantly is the cost per litre. Wiring all the parallel lines is quite annoying and introduces more potential for mistakes - the I²C version only has two wires for power and two wires for signal. Celsius/ Fahrenheit display selectable. That's another four or five gallons. 1 year ago. According to the datasheet, the sensor outputs 450 pulses per litre. I was thinking of using something similar for beer brewing :). We’ve seen how a smart water meter can help users track water usage, saving money and making houses more eco-friendly. Save $300 a Year or More. Be sure the nuts are very tight so that when you tighten the screws, the standoffs don't turn. 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 screwed four standoffs into the holes on the bottom of the enclosure with four M3 screws (see images 1 & 2). The millis() function returns the number of milliseconds since the Arduino was turned on. Replace the hot water stop in the faucet while the water continues to flow. Plus, there are M3 screws and nuts, so you don't need to buy any additional hardware. One touch to the right and you’re blasted with cold water. If you accidentally plug the charger into the sensor port, or vice versa, there won't be any damage to the device. The row of 16 header pins on the LCD should be on the top - make sure you don't mount the LCD upside down! The flow sensor has an arrow to indicate the intended direction of flow. The best source for transparent plastic that I've found is produce packaging. Any single-cell Li-Ion or LiPo battery will work, so long as it fits into your enclosure. If you don't have the luxury of a ledge or basket, you could try holding the device to the wall with a double-sided suction cup. In the photo of my oscilloscope you can see how the signal changes as the flow is turned on. If you're updating the LCD screen on a clock, it would quickly become inaccurate and fall behind. Single-function valve must be adjusted for each shower. The database approach is more complex but would let you perform analysis on the raw data. You can download the STL files from my Thingiverse page. 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. 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. By default, the cost is shown. Question Once this is done, to print the custom character we use the following line: The LCD can have up to 8 custom characters. After viewing product detail pages, look here to find an easy way to navigate back to pages you are interested in. To test, turn the shower on (both hot and cold) and carefully monitor leaking water under the shower. The flow sensor jack is on the side, but when the flow sensor is plugged in, the plug blocks water from entering the jack. 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. One tap to the left and scalding hot water has you hugging the shower wall. Some of these ideas are bordering on feature creep, which is why I didn't develop the software any further. I attached the charger and boost converter to the lid with double-sided tape, as seen in the third image. I was able to make the Arduino fit by placing it on its side, in the bottom left corner, with its USB port facing the right. I also used 100% infill. 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. Most types of valves have one, two or three outlets and they may be fitted into handheld or wall mounted shower heads. on Introduction. 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? Then solder a wire from the negative output (located beside the negative battery wire) to the master toggle switch's common (centre) pin. This will make it much easier to write the code. 1 year ago. I wanted an overhang of 5mm to give plenty of surface area for gluing, so I cut out a 27x77mm rectangle of clear plastic. 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. Shower Water Monitor Tracks The Dollars And Cents. Since it will reside in a shower, it must be able to survive extreme humidity and the occasional splash. All delta single lever shower faucets are similar. Pro-Tip: Add some Teflon plumber's tape to all the threads before screwing the pieces together to prevent leaks. While there's no water running, the front panel button shouldn't do anything besides clearing the total and clearing the screen. Run the dishwasher, too? As a precaution, direct the water into the drain only since you’ve tested this already and not at any walls or shower doors. 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.

They also have a built in WiFi adapter. These headers will allow us to connect the LCD screen using female-to-female jumpers. Once the transparent window has dried, the LCD can be mounted. Ultra-Practical Shower Thermometer: with this thermometer, we can take shower with just right water temperature, especially suitable for the family with babies. It's always good to make use of parts you have lying around. By creating a variable "previousMillis" and subtracting Millis() - previousMillis(), we can see the elapsed time since previousMillis was updated. Zoe+Ruth Non Contact Forehead and Ear Thermometer, Medical Grade Fast Accurate, Digital Infrared for Instant Temporal Fever Temperature for Baby, Kids & Adult. Next, I placed my Arduino Nano in the middle of the board and marked where the header pins went through. A shower diverter valve enables you to control the amount of water that goes into separate outlets on the shower head. 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. Once the shower stops, pressing the front panel button will reset the measurements and clear the screen. It is 3' long, which is the perfect length, and it has tinned wires, which makes it easy to solder. Then we exit this block of code and finish the rest of the loop() function, before going back to the start and repeating it all over again. Also, make sure you don't over-tighten the screws, or the plastic lid could deform and not seal properly. Finally, I soldered the sleeve to ground, the tip to +5V, and the ring to digital pin 2. Right now, the only indication that the device needs to be recharged is when the battery manager board cuts off the power. Shower Thermometer LED Water Temperature Digital Display Monitor, Water Flow Self-Generating Electricity Bath Water Thermometer Celsius Temperature Meter with 360° Rotating Screen for Baby Care (1pcs) dretec Digital Timer, Water Proof, Shower, Magnetic Backing, White, Officially Tested in Japan (1 Starter Lithium Battery Included) $14.99$14.99 Some USB cables will have four wires: red, black, green, and white.

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. When the flow starts, the frequency of pulses quickly comes up to speed and reaches a steady state. If your enclosure has a rough backing (like mine does), you could trying using some double-sided tape, although this might leave some residue on your shower wall if you try to remove the device. Now we're finished soldering, but we still need to hook up the LCD. Then you could see what times of the year people have more frequent and longer showers. So now that we understand the overall structure of the program, it's time to insert the instructions. https://www.banggood.com/G1-14-1_25-Water-Flow-Hal... Answer Every time the magnet passes by the hall-effect sensor, it toggles between high and low. Of course, you don't have to follow my steps exactly! Therefore, I was forced to create a custom character. After installing the lock-washer and tightening the nut, I soldered two wires to the "tip" and "sleeve" tabs on the connector. Which uses more water - a bath or a shower? This will allow us to remove the Arduino for programming. There are a few parts in the code you might want to change. I really like your instructable, but I have used somewhat easier and much simple approach to the same problem. Of course, if you're using an enclosure with a transparent lid, this isn't needed at all. The design is surprisingly simple and ingenious. I chose to use digital pins 2 and 3 for the button and flow sensor because they are hardware interrupt pins. Banggood - 100x68x50mm Box with Transparent Lid - $5.35, Digikey - 130x80x70mm Box with Transparent Lid - $11.65. The default character set does not include the "¢" character, and I didn't want to use dollars, because the cost would show up as "$0.01" or less for the majority of the time. I squirted a line of superglue around the perimeter of the cutout, and then placed the clear plastic on. I picked up this flow sensor from Banggood for $3.87. The Streamlabs Water Monitor is the ultimate solution for tracking your water consumption and providing real time alerts to possible leaks. Our products are designed to be easy to install and use. 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. Share it with us! 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. But now, it's time to head to the bathroom! Our cutoff valves use microchip technology to control the amount of time spent in the shower, as well as preventing immediate restarting. At first, the signal is constantly zero volts. My Delta Monitor shower and tub faucet has very low water output/pressure. I used more double-sided tape to secure the battery to the bottom of the enclosure beneath the LCD screen. Were you able to do this? I've included a complete wiring diagram, which you can follow, or see my written steps below if you prefer a more guided approach. Water providers have determined that long showers are one of the biggest water wasters in the home. Once you have the coupling, simply screw the flow sensor into the coupling, and then screw the other end of the coupling onto the pipe. I obtained the values from here: https://www.halton.ca/getmedia/0827acbc-dce9-4933-8bdb-7a5de3ae3199/PW-water-rate-card-2019.pdf.aspx?ext=.pdf. If you wanted more precision, you could use a different flow meter. This will be important later on when we are writing the software. 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 Nickel…. Next you will need a male 3.5mm plug. The LCD is a super popular 16x2 character display, with the I²C "backpack" pre-soldered to the back. In my city, the water costs 0.2523¢ per litre. The most difficult aspect of this project is making the whole thing waterproof. Next, turn on the master power switch. Once you've seen the flowchart, take a look at the attached Arduino code. 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 good (accurate) is that flow sensor? The way I see it, there are two choices: design a custom 3D printed enclosure, or try to make it work with an off-the-shelf enclosure. Reply 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.
