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 ...

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 digital optical liquid-level sensor is said to be versatile enough to be mounted at any angle and at the top, sides, or bottom of a vessel. Measuring just 30.25 mm x 19 mm, the sensor houses an ...

Some motion sensors are based on optical measurement technologies to provide accurate velocity and position measurements without requiring physical contact with the object or surface being monitored.
