Ultrasonic Module Distance Sensor For Arduino - $5.80

There are 4 pins out of the module : VCC , Trig, Echo, GND . So it's a very easy interface for controller to use it ranging. The all process is : pull the Trig pin to high level for more than 10us impulse , the module start ranging ; finish ranging , If you find an object in front , Echo pin will be high level , and based on the different distance,it will take the different duration of high level.

Product Features:

  • 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
