This project is based on Arduino UNO and an ultrasonic sensor. It is designed to measure distance and trigger a buzzer if the measured distance is below a certain threshold. The ultrasonic sensor ...

This project uses an HC-SR04 ultrasonic sensor to measure how close an object is. A buzzer and LED react depending on the distance, similar to a car parking sensor. < 10 cm → buzzer and LED stay on.

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 ...

Serial Kickstarter entrepreneur Patrick Thomas Mitchell has once again taken to Kickstarter to raise funds to take his new programmable Arduino ultrasonic experiment kit into manufacture. Once ...

Parking sensors have become a must-have these days given the crowded cities we live in, but instead of paying hundreds of dollars to get them installed in your car, why not build your own at home?

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 ...
