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 ...

This reference design describes a cost-effective, low-power liquid-level measurement data acquisition system (DAS) that use a compensated silicon pressure sensor and a high-precision delta-sigma ADC.

Ultrasonic sensors measure the distance between a target and the sensor using high-frequency sound waves that are inaudible to humans. The process is simple: the sensor emits ultrasonic waves, which ...
