Product description

SainSmart 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. So we can calculated the distance easily : Distance = ((Duration of high level)*(Sonic : 340m/s))/2

Specifiction:

– Power supply :5V DC

– Quiescent current : <2mA

– Effectual angle: <15°

– Ranging distance : 2cm ..500 cm

– Resolution : 0.3 cm
