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 ...

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 ...

This is an Arduino-based Proximity Sensor circuit wired using the popular HC-SR04 Ultrasonic ranging module,used here for non-contact object detection purpose. The HC-SR04 module includes ultrasonic ...

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 ...

Advocating radar technology as the better ultrasonic, Vega demonstrates how its radar sensors outperform under a variety of temperature, gas, pressure, and environmental conditions. Vega’s Greg ...

Ultrasonic close-range sensors have joined radar in the trash bin over at Tesla, which going forward will build its cars with only cameras onboard to power its driver assistance and collision ...
