Ultrasonic sensors continuously measure the distance to check for empty or occupied slots. If a slot is occupied, it is marked as unavailable. When a vehicle is detected at the entrance and slots are ...

This project combines a joystick, servo motor, ultrasonic sensor, two LEDs, and a buzzer to create an interactive object detection system. The joystick is used to rotate the servo motor left and right ...

Abstract: This research aims to develop a RADAR system using an ultrasonic sensor (HC-SR04), servo motor (SG90), and Arduino UNO. This RADAR system can detect objects in the vicinity and display ...

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 ...

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 ...
