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 Arduino sketch code is pretty simple even though I spent almost ... In the loop() we check to see if the water level has reached any sensor and if so then turn an the corresponding led. We also ...

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 ...
