By counting the pulses from the output of the sensor, we can easily calculate the water flow rate (in litre/hour – L/hr) using a suitable conversion formula. The Arduino Sketch (code) uses the ...

The most obvious way of measuring water consumption is to install an off-the-shelf flow meter onto your pipe ... thanks to a power-efficient Arduino Pro Mini and a BlueTooth Low Energy (BLE ...

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 LEDs, tamberg set up the device to change ...

Here is a tested Arduino ... connect the 3 leds. We connected the motor on pin A4 so we use this in our motor variable. Inside the setup() function we set the sensor pins as INPUT and led pins and ...
