Description

What better way to describe a product without having a story behind it?

Well…A few months ago, we thought of developing a water level sensor, but we wanted it to be different, unlike traditional water level sensing techniques such as using Ultrasonic Sensing and Resistance Based Sensing.

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

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

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

Let’s look at the difference between few water level sensing methods.
