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 ...

Check out the Avnet element14 competition In Reach! It's an "Ultrasonic Sensor Sensing Challenge". Ultrasonic The idea is for makers to build projects using TDK’s waterproof ultrasonic range sensors.

Ultrasonics refers to signals that are above the human hearing span (>20 kHz), and usually in the 40- to 70-kHz range. These signals are used like radar—they’re radiated toward a target and reflected ...

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 ...

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 ...
