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 ...

The basic design idea is to set two ports of the MCU for water level detection, one port for automatic/manual mode switch selection, and two ports for visual status indication. From the reading of 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.

Latest version consists essentially in an Arduino UNO, an ultrasonic distance sensor, and a DHT temperature/humidity sensor to provide calibration since these characteristics affect the speed of ...

Haya and Taha built a water level sensor. Watching their video (you’ll need to crank the volume) it dawns on us all of the great things that are learned in a project like this.
