  • Operating principle - Blocks hc-sr04 distance measuring transducer sensor, it consists of ultrasonic transmitter, receiver, and control circuit.
  • HC-SR04 ultrasonic sensor blocks module -- Using IO trigger for at least 10us high level signal, when triggered it sends out a series of 40KHz ultrasonic pulses and receives echo from an object, the duration of the signal is the time from sending ultrasonic to returning.
  • Test Distance Formula -- The distance between the unit and the object is calculated by measuring the traveling time of sound and output it as the width of a TTL pulse,hc-sr04 test distance following formula -- L = 1/2 × T × C ( L is the distance, T is the time between the emission and reception, and C is the sonic speed )
  • Package include -- 5 X HC-SR04 ultrasonic sensors blocks module, 10 X female-male cables , 10 X female-female cables , 3 X HC-SR04 mounting bracket
