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 ...

Automatic Water Tank Pump Switch Hardware • Microcontroller Unit: The designed circuit shown here includes an Atmega328P-PU as the kernel, a number of LEDs to display the system status, a push button ...

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 whole structure is made from 1/2″ PVC pipe and fittings and is broken into four nearly identical sensor modules. The sensors have an electrode on either side.

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

A leak sensor is a quick and affordable way to identify potentially damaging water leaks.

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.

Arduino simplifies things by only using just one coding language. Here's what you need to get started with developing software for the tiny device.
