In this project, the ultrasonic sensor module type KY-050 is used together with an Arduino and a type KY-012 active buzzer to help while reverse parking our vehicle. As the distance to the objects ...

EchoAlert is a simple Arduino project that detects nearby objects using an ultrasonic sensor and provides feedback through a buzzer. The system measures distance using the HC-SR04 ultrasonic sensor.

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 project builds a sweeping radar using an ESP32, a servo motor, an HC-SR04 ultrasonic sensor, and a passive buzzer. The servo rotates the sensor from 0 to 180 degrees continuously. At each angle ...
