SR04 Ultrasound Modul Sensor

SR04 Ultrasound Modul Sensor

Kode Produk:SSR019
Harga: Rp.40.000,00


Features :

Ultrasonic ranging module HC - SR04 provides 2cm - 400cm non-contact measurement function, the ranging accuracy can reach to 3mm. The modules includes ultrasonic transmitters, receiver and control circuit. The basic principle of work:

  •  Using IO trigger for at least 10us high level signal,
  •  The Module automatically sends eight 40 kHz and detect whether there is a pulse signal back.
  •  IF the signal back, through high level , time of high output IO duration is the time from sending ultrasonic to returning. Test distance = (high level time×velocity of sound (340M/S) /2
  • power supply :5V DC
  • quiescent current : <2mA
  • effectual angle: <15°
  • ranging distance : 2cm – 500 cm
  • resolution : 0.3 cm
