Description

The Obstacle Detector sensor module is perfectly adaptable to the environment light, IR
Object Avoidance Sensor has a pair of infrared transmitting and receiving tubes; transmitting tube
emits infrared in a certain frequency, when detecting direction meets with obstacles(reflecting
surface), reflected infrared will be received by the receiving tube; after the comparator circuit
processing, the green indicator will light up, at the same time signal output interface to output
digital signal(1 low-level signal). Users can adjust the detection distance through the
potentiometer knob, effective distance range 2~30cm and working voltage is 3.3V to 5V. The
Obstacle Avoidance module LM393 can be widely used in robot obstacle avoidance, obstacle
avoidance car, line count, black and white line tracking, and so on many occasions.

Pins Description:

1. VCC: 3.3V-5V external voltage (can be directly connected to 5v and 3.3v MCU MCU)
2. GND: GND External
3. OUT: small board digital output interface (0 and 1)
