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 ...

Traditional water level controller can control the water between two levels with the help of floating balls/float switch as the sensors for level detection. According to the positions of the floating ...

Calibrating the system using a bowl of clean water. There is no single parameter that determines the quality of a water sample, so the pollution monitor has no less than five different sensors.

The system has an Arduino commanding an irrigation system based around a pump delivering water from a reservoir. It’s paired with a water level sensor to keep an eye on the water available to ...
