Since the traditional water level controller has inherent problems, many people prefer digital electronics to detect and control the water level in an intelligent manner. Here is a simple yet ...

Here is a tested Arduino project that uses 3 sensor probes as water level indicator with 3 leds and one LCD display + a simple controller that turns on a motor when the water has reached the desired ...

As soon as the moisture level reaches upwards of 70%, the Arduino stops the water pump. This controlled water flow ensures the plant never gets too much or too little.
