HC-SR04 Ultrasonic Distance Sensor - 2cm to 400cm Range, Precise Object Detection

The HC-SR04 Ultrasonic Distance Sensor is a highly reliable sensor designed for measuring distances between 2 cm and 400 cm with an accuracy of up to 3 mm. Using ultrasonic sound waves, this sensor provides precise distance measurements by emitting sound pulses and calculating the time taken for the echo to return. The HC-SR04 is ideal for applications such as obstacle detection, automation, and robotics.

This sensor operates by transmitting an ultrasonic signal and measuring the time it takes for the sound to bounce back after hitting an object. It features four pins: VCC, Trig, Echo, and GND, making it easy to integrate with microcontroller platforms such as Arduino and Raspberry Pi. The compact design and high accuracy make it suitable for a wide range of projects, including distance sensing, object avoidance, and level detection.
