## Description

20 Pieces IR Infrared Obstacle Avoidance Sensor Module 3-Wire Reflective Photoelectric Sensor Module Compatible with Arduino/Raspberry Pi 3/Smart Car Robot

## Features

- 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)
- Function: the IR infrared obstacle avoidance sensor module can be applied in robot obstacle avoidance, obstacle avoidance car, line count, black and white line tracking, etc.
- Adjustable distance: the detection distance of the infrared module is 2 to 30 cm, and the detection angle is 35 degrees, the distance The distance at which the potential can be detected is adjustable
- Easy to use: the output port OUT sensor module can be directly connected to the microcontroller port, you can directly drive a 5V relay
- Application: the IR sensor module can be applied for 3-5V DC power supply modules; There is a red power indicator
