Package Included

- 1 x IR Infrared Obstacle Avoidance Sensor Module for Arduino

Description:

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 ~ 20cm, detection angle 35 °, the distance can detect potential is adjusted clockwise adjustment potentiometer, detects the distance increases; counterclockwise adjustment potentiometer, reducing detection distance.
2, the module can be 3-5V DC power supply. When the power is turned on, the red power indicator lights;

Module Interface 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)
