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 ...

8: Arduino Water Level Indicator 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 ...

LEDs on the Arduino can be programmed to indicate if the sensor is or isn’t immersed by the liquid to determine liquid levels. The devices are compact, allowing them to be deployed within constrained ...

He decided it was time to build his own solution to this problem. What he ended up with was a water level sensor made from PVC pipe and a few other components. The physical assembly is pretty simple.

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.
