Hi guys, i wanted a flowmeter for my rodi since with a AWC system is nice to know how many liter i've put in the saltwater reservoir in order to just weigh the salt and trow it in.... and also because, why not.
I've found a tutorial and i have adapted it to our needs with a smaller flow meter able to detect from 0.05lt/min, once calibrated is fairly precise (+-2/3%). And, other than the screen, is wifi and you can keep track of total production via a webpage and you can integrate it on HomeAssistant.
What you need (you can find everything on Amazon or Aliexpress):
- SSD1306 12864 4-pin 0.96 inch LCD - €3
- CP2102 MCU Node - €3.50
- sensor SEN-HZ06D 0.05-1.5l 5V - €4
- connectors (or soldering)
Optional to do this with a rechargeable battery (be careful, if you don't know how, stick to the USB version, it's not difficult but you absolutely need to know how to solder):
- 18650 lion
-bms 1S
-ON/OFF button
- external USB C port
Original tutorial: https://diyprojectslab.com/iot-water-flow-monitoring-esp8266/
If you would like to do this, message me and I will send you the code to program the Arduino specifically for this sensor and the STL file to print the box for you if you have access to a 3D printer.
NOTE :::::::::::::::: If anyone is good at programming with Arduino and would like to participate, I would like to modify it a little to make it perfect.
