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 system relies on two key components to make this happen: the Arduino and the soil moisture sensor ... the Arduino stops the water pump. This controlled water flow ensures the plant never ...

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 ...
