Ultrasonic sensors use sound waves above 20 kHz to measure the distance from the sensor to a specified target. The sensor transmits and receives sound via a ceramic transducer that acts like a ...

There is a lot of buzz about electromagnetic (EM) detection and ranging sensor technology, which encompass radar, lidar, infrared (IR), ultra-wide bandwidth (UWB), and many others. However, there are ...

Time-of-flight (ToF) sensors open up new application areas and use cases for proximity sensing and presence detection technologies, and these sensors can add valuable functionalities and intelligence ...

Ensuring safe social distancing is one piece of the puzzle for workers in the COVID-19 age. Ultrasonic range-finding sensors can measure the distance between workers with centimeter accuracy and alert ...

Inductive sensors are non-contact proximity sensors that detect ferrous targets, ideally ones made of mild steel thicker than one millimeter. They consist of four major components: a ferrite core with ...
