Ultrasonic Sensor HC-SR04

The HC-SR04 ultrasonic sensor uses sonar to determine distance to objects 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). Ranging accuracy can reach to 3mm.
