Arduino ir infrared obstacle avoidance sensor module

Arduino IR Infrared Obstacle Avoidance Sensor Module

The sensor module adaptable to ambient light, having a pair of infrared emitting and

receiving tubes, transmitting tubes emit infrared certain frequency, when the direction of an

obstacle is detected (reflection surface), the infrared reflected is received by the reception

tube, After a comparator circuit processing, the green light is on, but the signal output

interface output digital signal (a low-level signal), you can adjust the detection distance knob

1. When the module detects an obstacle in front of the signal, the green indicator lights

on the board level, while the OUT port sustained low signal output, the module

detects the distance 2 ~ 30cm, detection angle 35 °, the distance can detect potential is

adjusted clockwise adjustment potentiometer, detects the distance increases; counter

clockwise adjustment potentiometer, reducing detection distance.

2. The sensor active infrared reflection detection, target reflectivity and therefore the

shape is critical detection distance. Where the minimum detection distance black,

white, maximum; small objects away from a small area, a large area from the Grand.

3. The sensor module output port OUT port can be directly connected to the

microcontroller IO can also be directly drive a 5V relay; Connection: VCC-VCC;
