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 ...

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 ...

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 ...

Researchers have developed a sensor array design technology inspired by the human auditory system. By mimicking the human ear's ability to distinguish sounds through tonotopy, this innovative sensor ...

Apple has been granted a patent (number 11,346,940) that hints that the rumored “Apple Glasses” — an augmented reality/virtual reality head-mounted display — may have an ultrasonic sensor. In the ...

Researchers from The Hong Kong University of Science and Technology (HKUST) have developed a sensor array design technology inspired by the human auditory system. By mimicking the human ear's ability ...
