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 ...

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 ...

LEDs on the Arduino can be programmed to indicate if the sensor is or isn’t immersed by the liquid to determine liquid levels. The devices are compact, allowing them to be deployed within constrained ...
