The Korea Research Institute of Standards and Science (KRISS) has developed an ultrasonic sensor technology that applies a ...

This post is a review of the popular waterproof ultrasonic sensor JSN-SR04T. I hope this will serve as a backdrop for some interesting ultrasonic distance sensor experiments and projects. A number of ...

The options when specifying sensors for long-range object detection or positioning usually boil down to two alternatives: optical sensors using either infrared or visible-red light and ultrasonic.

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 ...

Ultrasonics or ultrasound is a radar-like system that uses ultrasonic signals at frequencies above those typical for human hearing, usually above 16 to 20 kHz. The 40- to 70-kHz range tends to be most ...

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 ...

For years, ultrasonic sensors have been used in a wide range of applications including fish finders, parking sensors in cars and burglar alarms. In this article, we describe the characteristics of ...
