Capacitive sensing is a contactless-sensing technique with numerous applications, ranging from proximity sensing (Fig. 1), gesture recognition, automotive rain sensors, and remote liquid-level sensing ...

The CLS 16 capacitive sensor controls liquid levels in nonmetal and metal tanks and tubs. It features an aluminum housing, a small 16-mm mounting diameter, and a short 8-mm behind-the-panel depth.

Recently I came across some non-contact liquid level sensors and gathered them out of curiosity. They have been available in the market for the past few years, but this time I was lucky enough to get ...

In the past, capacitive sensors for automotive electronics were rarely used, as they were deemed to be hard to control, difficult to read out, sensitive to aging, and temperature dependent. On the ...
