HiLetgo 5pcs HC-SR04 Ultrasonic Module Distance Sensor

  • The HC-SR04 ultrasonic sensor can send eight 40 kHz and detect whether there is any pulse signal back.If it back, a high level signal will be outputed by IO, and the duration of the signal is the time from sending ultrasonic to returning.
  • HC-SR04 Test Distance : high level time velocity of sound (340M/S) /2.
  • Equipped with anti-reverse pin socket – making the wiring much tighter and convenient.
  • Uses the MCU STC15W104 which has a built-in clock, no need of external crystal oscillator..
