The HC-SR04 Ultrasonic Distance Sensor is a must-have for any robotics or automation project that needs to detect obstacles or measure distance. It uses sonar to determine the distance to an object, working exactly like bats or dolphins do! It offers excellent non-contact range detection with high accuracy and stable readings. This module is incredibly easy to wire up to your favorite microcontrollers like Arduino, Raspberry Pi, or NodeMCU. It comes with a transmitter, receiver, and control circuit all on one tiny board, capable of measuring distances from 2cm up to 400cm with a precision of up to 3mm.
Detailed Specifications
The HC-SR04 provides excellent non-contact range detection, making it perfect for obstacle-avoidance robots, distance measuring devices, and automated smart dustbins. It works by sending out an ultrasonic pulse at 40kHz and listening for the echo. By calculating the time it takes for the sound wave to bounce back, your microcontroller can determine the exact distance of the object in front of it.
