Specification: Interface: 1. VCC: external 3.3-5 voltage (can be directly connected to 5v MCU and 3.3v MCU) 2. GND: GND external 3. OUT: small board digital output interfaces (0 and 1) Connection : VCC-VCC; GND-GND; OUT-IO Board size: 3.1 x 1.5 cm/ 1.22 x 0.59 inch, with the screw holes of 3mm, easy fixed installation Feature: The IR Infrared Obstacle Avoidance Sensor Module detection range can be through the potentiometer to adjust and have small interference, easy to assemble, easy to use. It can be widely used in robot obstacle avoidance, obstacle avoidance car, line count, and black and white line tracking and so on. 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 - 30 cm, detection angle 35 degree, the distance can detect potential is adjusted clockwise adjustment potentiometer, detects the distance increases. Counterclockwise adjustment potentiometer, reducing detection distance. Usage: Can be applied for 3-5V DC power supply modules. When the power is turned on, the red power indicator light. Using the comparator LM393. Each module has been shipped threshold comparator voltage adjusted by potentiometer good, non-special case, do not adjustable potentiometer. Package included: 15 x Infrared obstacle avoidance module

The output port OUT sensor module can be directly connected to the microcontroller IO port, you can directly drive a 5V relay. It can be used for 3-5V DC power supply modules. It has red power indicator. Detection distance is 2 ~ 30 cm, 35 degree Angle, distance can be adjusted through the detection of potential. Feature: there is a pair of infrared transmitting and receiving tube of the IR sensor module, tube infrared emit a certain frequency, when the detection direction meets the 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). IR Infrared Obstacle Avoidance Sensor Module can be widely used in robot obstacle avoidance, obstacle avoidance car, line count, and black and white line tracking and so on.
