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 ...

This is a simple arduino project for a soil moisture sensor that will light up a LED at a certain moisture level. It uses Arduino Duemilanove microcontroller board. Two wires placed in the soil pot ...

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

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.

The Fibaro Flood Sensor is a great HomeKit-compatible way to monitor your home for leaking water, but Bluetooth connection may be too limited for some.

Place Ring Flood and Freeze Sensors anywhere water might leak–such as under a kitchen sink–or where cold temperatures could freeze your water pipes, putting them at risk of bursting.
