Ultrasonic Distance Measuring Transducer Sensor – HC-SR04



The HC-SR04 sensor uses ultrasonic sound waves to determine distance to an object, like bats or dolphins do. It offers excellent range, accuracy and stable readings in an easy-to-use package. Its operation is not affected by sunlight or black material like IR rangefinders are (although acoustically soft materials like cloth can be difficult to detect).
