Sometimes we need a non-contact liquid level sensor. There are several ways to build that, but the easiest is to try an optical liquid level sensor. You may already have an idea in mind since you are ...

Reliable liquid detection is an essential requirement in many industrial sectors, including plant engineering. To meet these ...

Position Sensors play an important role in our daily lives. A position sensor, as the name indicates, provides feedback on the position of the measurand by detecting the presence/absence of an object ...

They do so by sending a small current through their probe tip. Current flowing between the sensor and some reference (often the metal tank holding the liquid) is compared inside the sensor to current ...

A way to apply the output of certain sensors to a TTL/CMOS-level iput on a microcontroller. Sensor must have an NPN output stage that can support a pullup to its power rail. With just a few components ...
