1. Water Level Sensor for Leak Detection . Electronics and water are famous for their destructive relationship, but this first sensor puts this common conception to the test.

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 ...

A low-cost (~$100), do-it-yourself (DIY) ultrasonic water level sensor/datalogger has been designed, constructed, and tested for use in education, citizen/community science, and research settings. The ...

My water level maintenance consists of dropping a garden hose in the pool and letting it run for 30 minutes; I have to do this less than once a month. But like I said, it's a cool project.
