Next we connected the water flow sensor’s output to the Arduino board (filled with the sketch) and allowed water flow through the water flow sensor at a steady rate of about 1 Litre/minute. Besides ...

The flow meter allows a hard limit to be set for the maximum amount of water allowed into the tank. He’s used an Arduino Micro to tie the project together, which also handles a real-time clock ...

To reduce power usage to a minimum, a flow switch was added in series with the flow meter, which only switches on the ESP8266 when water starts flowing.

If you're looking for ways to use less water, Instructables user tamberg developed a DIY water faucet sensor that shows you when you've used up a liter. Using an Arduino, flow sensor, and colored ...
