DESCRIPTION

Seeed wanted to develop a water level sensor, but they wanted it to be different for traditional water level sensing techniques such as Ultrasonic Sensing and Resistance Based Sensing.

They have tested out different water level sensing methods such as using Non-contact capacitance-based sensing where they placed the sensor outside the container filled with liquid and also use a Carbon Stick to detect the water level.

But they figured that the results achieved were not up to expectations and after a long period of use, the Carbon started to chemically react with water which made this technique not ideal.

So, they finally came up with a solution by using a Capacitance Sensing technique. They used capacitive pads on the PCB of the module and added a conformal coating over the PCB to make the sensor protected against moisture, dust, chemicals and high temperatures. They believe that this technique will allow you to make accurate water level measurements (±5mm accuracy) easily.
