Introducing the IR Infrared Obstacle Avoidance Sensor Module for Arduino Smart Car Robot, the perfect addition to your Arduino sensor kit. With its 3-wire reflective photoelectric design, this sensor module offers a wide range of applications, including robot obstacle avoidance, line counting, and black and white line tracking. What sets this module apart is its effective distance range of 2 ~ 30cm and a detection angle of 35°, ensuring accurate and efficient obstacle detection. The module features a green indicator light that illuminates when an obstacle is detected, accompanied by a sustained low signal output on the OUT port. The detection distance can be easily adjusted using the clockwise or counterclockwise adjustment potentiometer, providing flexibility in various scenarios. The sensor module utilizes active infrared reflection detection, making it highly sensitive to target reflectivity and shape, allowing for precise detection distances. From detecting black and white surfaces to distinguishing small and large objects, this module adapts to different conditions with ease. Installation is a breeze, thanks to the 3mm screw holes, ensuring a secure and fixed installation. The board size of 3.2CM * 1.4CM makes it compact and convenient for integration into your Arduino car or inspection robot. With its LM393 comparators, the module offers stability and reliability, ensuring accurate readings. The VCC-VCC and GND-GND connections simplify the setup, while the OUT-IO interface allows for easy integration with microcontrollers or driving a 5V relay directly. This module can be powered by a 3-5V DC power supply, and the red power indicator light provides a visual confirmation of power status. Each module is shipped with a threshold comparator voltage adjusted by the potentiometer, eliminating the need for additional adjustments in most cases. ## Features - Enhance your Arduino car project with our IR Infrared Obstacle Avoidance Sensor Modules, designed for seamless integration and optimal performance, ensuring your smart vehicle adeptly navigates any course with precision. - Elevate your Arduino sensor kit with our reflective photoelectric proximity sensor, offering a reliable 2-30cm detection range, ideal for sophisticated inspection robot systems requiring meticulous distance sensing. - Our versatile distance sensor modules are perfect for line tracking and count tasks, delivering consistent results and easy installation for both hobbyist and professional Arduino smart car robot applications. - With an adjustable detection range and a stable LM393 comparator, our proximity sensor is a crucial component for any Arduino sensor kit, ensuring your creations respond swiftly to their surroundings. - Tailor your Arduino projects with precision using our sensor modules, equipped with easy-to-mount screw holes and straightforward 3-wire connectivity, making them a must-have for any Arduino car enthusiast or robotics engineer. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0CWKWWKYL | | Best Sellers Rank | #353 in Single Board Computers (Computers & Accessories) | | Brand | EC Buying | | CPU Manufacturer | STMicroelectronics | | CPU Model | Cortex | | Compatible Devices | Arduino | | Connectivity Technology | Infrared | | Customer Reviews | 4.7 out of 5 stars 31 Reviews | | Manufacturer | EC Buying | | Operating System | Linux, Windows | | Processor Brand | STMicroelectronics | | Processor Count | 1 | | RAM Memory Technology | LPDDR4 | | Total Usb Ports | 3 | | Wireless Communication Standard | Infrared | | Wireless Compability | Infrared | ## Product Details - **Brand:** EC Buying - **Connectivity Technology:** Infrared - **CPU Manufacturer:** STMicroelectronics - **Wireless Communication Standard:** Infrared - **Processor Count:** 1 ## Images ![20pcs IR Infrared Obstacle Avoidance Sensor Modules for Arduino - Reflective Photoelectric Proximity Sensor, Ideal for Smart Car Robot, Arduino Car Distance Tracking,3.3V-5V DC - Image 1](https://m.media-amazon.com/images/I/71flm8dP-RL.jpg) ![20pcs IR Infrared Obstacle Avoidance Sensor Modules for Arduino - Reflective Photoelectric Proximity Sensor, Ideal for Smart Car Robot, Arduino Car Distance Tracking,3.3V-5V DC - Image 2](https://m.media-amazon.com/images/I/41FQEZ8aj+L.jpg) ![20pcs IR Infrared Obstacle Avoidance Sensor Modules for Arduino - Reflective Photoelectric Proximity Sensor, Ideal for Smart Car Robot, Arduino Car Distance Tracking,3.3V-5V DC - Image 3](https://m.media-amazon.com/images/I/51uJ7tYsm+L.jpg) ![20pcs IR Infrared Obstacle Avoidance Sensor Modules for Arduino - Reflective Photoelectric Proximity Sensor, Ideal for Smart Car Robot, Arduino Car Distance Tracking,3.3V-5V DC - Image 4](https://m.media-amazon.com/images/I/41EsJBJ1bdL.jpg) ![20pcs IR Infrared Obstacle Avoidance Sensor Modules for Arduino - Reflective Photoelectric Proximity Sensor, Ideal for Smart Car Robot, Arduino Car Distance Tracking,3.3V-5V DC - Image 5](https://m.media-amazon.com/images/I/41NLRg08cAL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by S***S on February 4, 2026* ### ⭐⭐⭐⭐⭐ Review *by J***K on May 13, 2025* ### ⭐⭐⭐⭐ Review *by N***M on April 28, 2024* ## Frequently Bought Together - EC Buying 20pcs IR Infrared Obstacle Avoidance Sensor Modules for Arduino - Reflective Photoelectric Proximity Sensor, Ideal for Smart Car Robot, Arduino Car Distance Tracking,3.3V-5V DC - EDGELEC 120pcs Breadboard Jumper Wires 10cm 15cm 20cm 30cm 40cm 50 cm 100cm Wire Length Optional Dupont Cable Assorted Kit Male to Female Male to Male Female to Female Multicolored Ribbon Cables - ELEGOO MEGA R3 Board ATmega 2560 + USB Cable Compatible with Arduino IDE Projects RoHS Compliant --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pe/products/621157417-20pcs-ir-infrared-obstacle-avoidance-sensor-modules-for-arduino-reflective](https://www.desertcart.pe/products/621157417-20pcs-ir-infrared-obstacle-avoidance-sensor-modules-for-arduino-reflective) --- *Product available on Desertcart Peru* *Store origin: PE* *Last updated: 2026-05-18*
