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 ...

After some searching, I ended up using a microcontroller and a piece of code borrowed from the web that I tweaked and adapted. The microcontroller-based concept was chosen because I wanted to scale ...

There are a flame sensor and a water pump up forward, as well. You can probably guess, the device notices a flame and rushes to squirt water on it. That got us thinking, though.

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