The HC-SR04 Ultrasonic Sonar Sensor Module is a highly popular and reliable module for distance measurement applications. Using ultrasonic sound waves, it accurately detects objects and measures distances from 2cm up to 400cm (4 meters) with a resolution of just a few millimeters.
This sensor operates by sending out an ultrasonic pulse and measuring the time it takes for the echo to return. It features a simple 4-pin interface (VCC, Trig, Echo, GND) and is easily compatible with Arduino, Raspberry Pi, and other microcontrollers.
Whether you're building an obstacle-avoiding robot, an automated parking assistant, or a smart measurement device, the HC-SR04 delivers accuracy and performance at a great value.
