Therefore there is a need for Monitoring Water Management System Online. Hi, are you using the same version of the water flow sensor? Similarly using MQTT Protocol better wireless communication can be achieved. Every time the magnet passes and LED lights up means that a full cycle has occurred. Try check by changing the I2C address in Code. However, its great for basic measurement tasks! 468). In my case: Ex. Now lets get started. Wire colors can be slightly different, Ive seen both orange and pink be used for ground. Is there a chance to combine your two projects that I have given the web link below? there is then another error related to this one [ In function void setup(): yes same error for me also.. can anyone clearup? Probably you need to calibrate your sensor and formulas a bit. The utility meter sensor provides functionality to track consumptions of various utilities, including water. The flow meter says 3,800L/hr. I would also prefer a brass sensor, but these things are unfortunately not easily available in my country. The sensor filter divides the incoming pulse rate by 27 (because we know its 27 pulses per litre) and then multiplies by 60 to get the value per hour. Flash your Wemos D1 Mini Pro or ESP8266 with Tasmota. How do I use interrupt service routines inside libraries and classes? We will then integrate the hardware with IoT Server. Am I on the right track? Hi, your wifi ssid and password probably is going to be on your wifi router. But now let us see the IoT Water Flow Meter Circuit Diagram & Connection. Assuming that you already have a MQTT server such as Mosquitto. The unit is plastic. Please!! It works, but I wish I could make that calculation a little more elegant. The sensor operates in cycles that can be defined. The module itself only supports 1-30L/min floRate only. Luckily the meter provides a spinning wheel that contains a magnet. This sensor sits in line with your water line that you want to measure and contains a pinwheel sensor to measure how much liquid has moved through it. The reason I say this is that simply by hooking the sensor up to the board and defining it in the yaml (ie: this is a pulse counter) I was getting pulses per minute back from it. In your Home Assistant navigate to Configuration-->Integrations-->MQTT select the device, then MQTT Info and take note of the Sensor info inside Entities --> Subscribed topics --> tele/YOUR-DEVICE-NAME_ClientID/SENSOR.

The Computer-Aided Design ("CAD") files and all associated content posted to this website are created, uploaded, managed and owned by third-party users. Like, when I measure by catching the water in a 20L jug and timing how long that takes, it seems to be very, very wrong. This blog is intended to provide a semi-permanent point in time snapshot and manifestation of the various thought and solutions that are in our minds, and as such anycode, solutionsand opinions/thoughts expressed within out-of-date posts may not the same, nor even similar, to those I may hold today. In my case; 1 pulse == 0.0001 M3 x 10 == 1 liter. BUT - after uploading the original code (before adding Telegram changes ), an error occurs during code run : ISR not in IRAM! On the left side, the three connectors are for the flowmeter, and the trigger and echo pins of the ultrasonic Im using to measure how much water is in the reservoir. so plzz send code Thanks for contributing an answer to Arduino Stack Exchange! Please check it. water_flow:82:50: error: pulseCounter was not declared in this scope Now I just need to figure out the formula to translate pulses into Litres/hr, which I think I can do right there in the ESPhome config. I installed chirpstack lorawan server. So for every litre of water which passes through it 27 pulses should be read. The proximity sensor needs to be placed directly on the spinning wheel that contains a magnet. Hi @Puneit_Thukral, thank you for your encouragement. A proximity sensor recognizes proximity of metal. It is reporting pulses to HA just fine. is it supposed to work as it is or you made an ommission, Yes, you need this under the setup function. Is there some sort of calibration thingy that I ought to be doing? In this card you can also click show more. Did you find a solution for this? The sensor works at 5V & can be connected to Vin of ESP8266. All of that is just to clean the power supply and protect the D1 from spikes. Love this tutorial! Anyway, so far so good. The best implementation for this use case is Wemos D1 mini PRO, since a large WiFi range required. My silicone mold got moldy, can I clean it or should I throw it away? I think a lot of the work youre describing has already been done in ESPhome. Its also important to make sure you buy a 5V version so you can power the sensor directly from the ESP. Hi @wellsy, thank you for posting those specs. I had a little trouble to begin with because I was trying to power the sensor from the Wemos 5V out, which it didnt enjoy. I use the following Lovelace configuration to show the water usage. The first counter will count to 27 and then deliver one pulse to the second counter (litres cumulative counter) and at the same time reset itself to zero and commence counting again. Settled down, and now my ghetto jug measurements are within error bars of the digital. In my case, I connected to GPIO2, i.e D4. The PCB quality are clean and brilliant. Im using this flow meter which includes a resistor on the unit which, I believe, makes it unnecessary to put one on the board. See the picture below. I am using a Wemos D1 R2, and a YF-DN40 water flow sensor (the big one). This being so, converting that data into L/hr was achieved with a very basic lambda.
(adsbygoogle = window.adsbygoogle || []).push({});
Now you can monitor the Water Flow Rate & Volume Data on Thingspeak Server as well. But oddly, not as beautiful as the previous one. I tried to change Pin - but still getting this error, This happens because of conflicts between Serial and external interrupts Let me know how you use the watermeter and what Lovelace configuration you use to visualize the water usage. Do you have any idea why this can happen? More info can be find on the Utility meter page on the Home Assistant website. In these reports you can filter down on selected times and get more insights. The specification of YF-S201 shows Output type is 5V TTL and you connect directly to GPIO2 port which is only 3.3V. Theres just a analog counter. Truly, this software is a marvel. This will provide you with a pulse, every pulse is equal to what has been defined by the meter. This is very important, it will be required in Code Part. To build the water usage meter were going to execute following easy 5 steps: ESPHome is a system to control your ESP8266/ESP32 by simple yet powerful configuration files and control them remotely through Home Automation systems like Home Assistant. The ESPHome configuration editor will now show. Not allowed to board flight because of no UK entry Visa, Transform characters of your choice into "Hello, world!". The pulse signal is a simple square wave so its quite easy to log and convert into liters per minute using the following formula. Which book should I choose to get into the Lisp World? For viewing the measurements in my lovelace dashboard I used a custom card called mini-graph-card, this card can be easily installed using HACS. Before I go barking up the wrong tree, is the Pulse Counter the right component to use? please help, Hi Sir, Even the YF-DN40 was extremely expensive - I could have bought 10 Wemos D1s for the same money. This sensor can be connected to the waterline as it has both inlet and outlet. it helped me a lot!! What do you need to build the solution. The sensor has a red LED light on top, the led will turn one when the magnet passes. Thank you for the reply sir!! You can keep repeating for 24hr or 7 days etc. The PCB for this project has been designed in EasyEDA online PCB making tool. I keep getting this message: Arduino: 1.8.12 (Windows 10), Board: NodeMCU 1.0 (ESP-12E Module), 80 MHz, 115200, 4M (3M SPIFFS), TST1:34:16: error: expected initializer before pulseCounter. hello sir. I finally got it deployed in the wild; its about 60 metres from the house in a box, and working. This will bring you to the historic reports.
