The HC-SR04 ultrasonic sensor uses sonar to determine distance to an object - just like bats or dolphins do. This module offers excellent range accuracy and stable readings in an easy-to-use package. Its operation is not affected by sunlight or black material (although acoustically soft materials like cloth can be difficult to detect).
The HC-SR04 Ultrasonic Sensor is an affordable proximity/distance sensor that can be used for object avoidance in various applications from robotics to multi-rotors. The module has integral ultrasonic transmitters, receiver and control circuit and is for use in conjunction with Ardupilot Mega or PixFalcon PX4 boards.
Perfect for collision avoidance on your next robotics or multirotor project!
