10 Stück Ultraschallmodul HC-SR04 Entfernungsmesswandler Sensor 5 V
Description: This is a commonly used ultrasonic sensor that detects the presence of obstacles in front and detects the detailed distance between the sensor and the obstacle. Its principle is the same as bat flying, that is, the ultrasonic module sends out an ultrasonic signal that is very high in frequency and cannot be heard by the human body. If the signals of these ultrasonic waves hit the obstacle, they will be reflected back immediately. After receiving the returned information, the distance between the sensor and the obstacle is calculated by judging the time difference between the transmitted signal and the received signal. The sensor is compatible with various microcontroller control boards. Package Included: 10 x HC-SR04 Ultrasonic Sensor module.
