Description:
The IR obstacle sensor module has a pair of infrared transmitting and receiving tube, tube infrared emit a certain frequency.
When detecting direction meet with obstacles (reflecting surface), reflected infrared receiving tube, after the comparator circuit processing,
green indicator will light up, at the same time signal output interface to output digital signal (a low level signal)；

When power on, the red power indicator light up.

Module parameters
Effective detection range: 2 ~ 30cm
Detection Angle: 35°
Working voltage is 3.3V to 5V
Comparator: LM393, working stable
Circuit board size: 3.2cm*1.4cm
Screw holes: 3 mm, easy fixed, installation

Advantage
The sensor detection range can be through the potentiometer to adjust and have small interference, easy to assemble, easy to use, etc.

Applications
Can be widely used in robot obstacle avoidance, obstacle avoidance car, line count, and black and white line tracking and so on many occasions.

Distance adjust
Test distance can be adjusted through the potentiometer, adjustable potentiometer clockwise, the detection distance increases;
Counter-clockwise tuning potentiometer, detection distance is reduced.

Package Included:
10 X IR Infrared Obstacle Avoidance Sensor Module
