Water Level Sensor ARDUINO

If you’ve ever had a water heater explode or attempted to build submersible electronics, you know how important it is to detect the presence of water.

That is exactly what this Water Level Sensor allows you to do! It can measure the water level, monitor a sump pit, detect rainfall, and detect leaks.

Let’s look into this sensor in more detail.

Hardware Overview

The sensor has ten exposed copper traces, five of which are power traces and the remaining five are sense traces. These traces are interlaced so that there is one sense trace between every two power traces.

Normally, power and sense traces are not connected, but when immersed in water, they are bridged.
