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 are designing your own intelligent “Graden Computer” with an optional digital plant moisture sensor/water ... user when it is time to water a potted plant, and/or turn on a water pump to quench ...

When the sensor detects that the moisture content is already below 30%, it sends a signal to the Arduino, which, in turn, activates a water pump to provide hydration to the plant. As soon as the ...
