Description The HC-SR04 ultrasonic sensor uses sonar to determine the 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). Perfect for collision avoidance on your next robotics or multi-rotor project! Specifications Power: 5V DC Quiescent Current : Show more
