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 ...

He decided it was time to build his own solution to this problem. What he ended up with was a water level sensor made from PVC pipe and a few other components. The physical assembly is pretty simple.

It runs on an Arduino MEGA 2560 PRO (or similar microcontroller) and supports a wide array of additional hardware including pressure transducer, water level sensor, flow meter, OLED display, and more.

The Arduino Plant Watering System is designed to automatically supply water to your plant's soil once its moisture level falls below a particular point. The system relies on two key components to ...
