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 ...

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 ...

The highest level of (reasonable) complexity would be a Kalman Filter. This is what you will find as the mathematical core in "sensor fusion" algorithms.

I've just come across a no-name non-contact, high-precision 80 GHz mmWave radar sensor for liquid level detection with a 40m ...
