HC-SR04 Ultrasonic Distance Sensor Module – High-Precision Ranging Detector for Arduino, Raspberry Pi, and Robotics Projects
HC-SR04 Ultrasonic Distance Sensor Module – High-Precision Ranging Detector for Arduino, Raspberry Pi, and Robotics Projects
The HC-SR04 Ultrasonic Distance Sensor Module is a widely used and highly accurate range detection sensor that measures distances using ultrasonic sound waves. It is ideal for use in robotics, automation, obstacle avoidance, and distance measurement applications. Compatible with Arduino, Raspberry Pi, and other microcontrollers, the HC-SR04 provides fast and reliable distance data for a wide range of DIY and professional projects.
Using ultrasonic wave reflection, this module calculates distance by emitting an ultrasonic pulse and measuring the time it takes for the echo to return, providing non-contact distance measurements with high precision.
