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 ...

Here is a tested Arduino project that uses 3 sensor probes ... on a motor when the water has reached the desired level (the highest in our case). You can use only the leds if you want, the lcd is ...

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 ...
