Radar System Using ESP8266, Ultrasonic Sensor (HC-SR04), Servo Motor (SG90), and Blynk Control This project demonstrates a real-time Radar System built using the ESP8266 NodeMCU, HC-SR04 ultrasonic ...

The ultrasonic distance sensor (HC-SR04) is a widely used electronic component for non-contact distance measurement. It operates on the principle of echo-ranging, where it emits an ultrasonic pulse ...

An evaluation kit from TDK showcases its USSM1.0 PLUS-FS ultrasonic sensor module for designs requiring obstacle detection and distance measurement. The sensor operates in harsh industrial ...

Infrared certainly has its uses, but if you’re trying to locate objects, ultrasonic detection is far superior. It’s contact-less, undetectable to the human ear, and it isn’t affected by smoke, dust, ...

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 ...
