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 ...

If you’d like to get some hard data on your water usage, have a look at [Josh EJ]’s Sensible Flow project. It contains designs for a set of sensors ... a power-efficient Arduino Pro Mini ...

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 ...
