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 ...

I built a mini radar system using Arduino UNO, HC-SR04 Ultrasonic Sensor, and SG90 Servo Motor, paired with a JavaScript-based visualization dashboard 🖥️. The servo sweeps from 0° to 180°, collecting ...

The sensor operates by beaming ultrasonic sound waves through the material from one side and measuring the intensity of the sound detected on the other side. Technically speaking, double-sheet ...

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 ...

Ultrasonic double-sheet detectors distinguish between single and double sheets of paper, plastic, or metal foils to prevent waste or machine damage. The sensor operates by beaming ultrasonic sound ...
