## Overview

This IR Infrared Obstacle Avoidance Sensor module features a pair of IR transmitting and receiving tubes with adjustable detection range from 2 to 30cm, powered by 3.3-5V DC. Designed for seamless integration with microcontrollers and relays, it offers strong ambient light resistance and a compact form factor, making it ideal for robotics, smart cars, and automation projects requiring reliable obstacle detection.

## Description

1. When the module detects an obstacle in front of the signal , the green indicator light on the board level , while low-level continuous output signal OUT port , the module detects the distance 2 ~ 30cm, detection angle 35 °, the distance can detect potential is adjusted clockwise adjustment potentiometer to detect the distance increases ; counterclockwise to adjust the potentiometer to reduce the detection distance . 2 .active infrared sensors to detect the reflected , and thus the shape of the reflectivity of the target detection range is critical . The minimum detection distance which black , white maximum ; small objects from a small area , a large area from the Grand . 3 . the output port OUT sensor module can be directly connected to the microcontroller IO port , you can directly drive a 5V relay ; Connection : VCC-VCC; GND-GND; OUT-IO 4 .using the comparator LM393, stable ; 5 .can be used for 3-5V DC power supply modules . When the power is turned on, the red power. Package Included: 2 x Smart car Obstacle avoidance Infrared Sensor module.

Review: Reflective Plate - By simply placing an Infrared Sensing Stickers, the range is much greater than 12 inches.
Review: Overpriced. - There are equivalent offerings available at a much lower price. The divergence of the IR LED beam - like most 5 mm LEDs - is about +- 30 degrees. Consequently, the detection range is limited to about 5-6 inches, as advertised. (Note: Polishing the LED flat increases the beam divergence to about +- 60 degrees.) Also, black objects tend not to reflect well at the wavelength (0.9 um) of the IR LED, and so are not seen. I converted this product into a broken-beam sensor by demounting and remoting the LED and photodiode facing each other. The broken-beam sensor I made works at a separation up to roughly 11-12 inches.

## Features

- ☆The sensor module has strong ability to adapt to ambient light. It has a pair of infrared transmitting and receiving tubes. The transmitting tube emits infrared light of a certain frequency.
- ☆Signal output interface outputs a digital signal (a low-level signal). The detection distance can be adjusted by the potentiometer knob. The effective range is 2 to 30cm and the working voltage is 3.3V.5V.
- ☆The sensor's detection distance can be adjusted by a potentiometer, has small interference, is easy to assemble, and is easy to use.
- ☆It can be widely used in robots to avoid obstacles, avoid cars, count pipelines, and track black and white lines.
- ☆Sensor module output port OUT can be directly connected with the microcontroller IO port can also directly drive a 5V relay; connection mode: VCC-VCC; GND-GND; OUT-IO.

### ⭐ Don't work
*by D***. on April 10, 2025*

Total waste of money. Doesn't really work and if you see some reviews stating how good it is and works, be weary. I sent it back.
