Product description

Feature:
There are 4 pins out of the module: VCC , Trig(control side), Echo(receiver),out (empty) 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:

The test distance = (Duration of high level * speed of sound (340M/S))/2

Module details:
Voltage: DC5V;
Static current: Less than 2mA;
Output signal: Electric frequency signal, high level 5V, low level 0V;
Sensor angle: Not more than 15 degrees;
Detection distance: 2cm-450cm
High precision: Up to 0.3cm

Package includes:
2X Ultrasonic Module
