Ultrasonic Sensor (HC-SR04)

The HC-SR04 Ultrasonic Sonar Sensor is a widely used module for accurate distance measurement and object detection. It combines an ultrasonic transmitter, receiver, and control circuit in a single compact unit. Using sonar technology, it determines the distance to an object by measuring the time it takes for sound waves to reflect back to the sensor.

With a sensing range of 2 cm to 400 cm and an accuracy of up to 3 mm, the HC-SR04 is suitable for a variety of applications including obstacle avoidance, level detection, and navigation systems. It operates reliably in various lighting conditions and is unaffected by sunlight or dark surfaces, though soft materials like cloth may reduce detection accuracy.

The module features four simple pins: VCC, Trig, Echo, and GND, making it easy to interface with microcontrollers such as Arduino. Its stable performance and low power consumption make it a dependable choice for both hobbyists and professionals.
