HC-SR04 Ultrasonic Sensor
Used for robotics, arduino projects, parking assistants, industrial applications (eg. grain or woodchips storage level).
The HC-SR04 ultrasonic sensor uses sonar 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. It operation is not affected by sunlight or black material like Sharp rangefinders are (although acoustically soft materials like cloth can be difficult to detect).
