HC-SR04 Ultrasonic Distance Sensor.
Product Link: HC-SR04 Product Page Datasheet: HC-SR04 Datasheet
HC-SR04 ultrasonic sensor provides a very low-cost and easy method of distance measurement. It measures distance using sonar, an ultrasonic (well above human hearing) pulse (~40KHz) is transmitted from the unit and distance-to-target is determined by measuring the time required for the echo return. This sensor offers excellent range accuracy and stable readings in an easy-to-use package.
