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 ...

Modern industrial systems have a multitude of sensors, switches, buttons and other low-frequency inputs that need continual monitoring. The network of input devices that an industrial system (such as ...

The signal attenuates severely when passing through air, but the presence of liquid greatly enhances transmission. Thus signal strength of the ultrasonic burst serves as the sensing mechanism. Upon ...
