Designed for smart cars and robotics, it boasts strong ambient light resistance and easy integration, making it a must-have for precision obstacle detection in DIY and professional projects. ## 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. ## 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. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07PFCC76N | | Best Sellers Rank | #232,352 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #124 in Photoelectric Sensors | | Brand | Generic | | Compatible Devices | Microcontroller, Robot, Smart Car | | Customer Reviews | 4.2 4.2 out of 5 stars (39) | | Item Weight | 0.01 Kilograms | | Manufacturer | Generic | | Maximum Range | 30 Centimeters | | Mfr Part Number | IR | | Model Number | IR | | Smart Home Compatibility | Not Smart Home Compatible | | UPC | 682228946447 | | Unit Count | 2.0 Count | ## Product Details - **Brand:** Generic - **Compatible Devices:** Microcontroller, Robot, Smart Car - **Item Weight:** 0.01 Kilograms - **Manufacturer:** Generic - **Maximum Range:** 30 Centimeters ## Images ![IR Infrared Obstacle Avoidance Sensor (2pcs) IR Transmitting and Receiving Tube Photoelectric Switch 3-pin Compatible with Ar-duino Smart Car Robot - Image 1](https://m.media-amazon.com/images/I/61uejxAxY2L.jpg) ![IR Infrared Obstacle Avoidance Sensor (2pcs) IR Transmitting and Receiving Tube Photoelectric Switch 3-pin Compatible with Ar-duino Smart Car Robot - Image 2](https://m.media-amazon.com/images/I/616F2To42YL.jpg) ![IR Infrared Obstacle Avoidance Sensor (2pcs) IR Transmitting and Receiving Tube Photoelectric Switch 3-pin Compatible with Ar-duino Smart Car Robot - Image 3](https://m.media-amazon.com/images/I/61E0Ke2bTuL.jpg) ![IR Infrared Obstacle Avoidance Sensor (2pcs) IR Transmitting and Receiving Tube Photoelectric Switch 3-pin Compatible with Ar-duino Smart Car Robot - Image 4](https://m.media-amazon.com/images/I/61RwPfJbM7L.jpg) ## Available Options This product comes in different **Number Of Items** options. ## Frequently Bought Together - IR Infrared Obstacle Avoidance Sensor (2pcs) IR Transmitting and Receiving Tube Photoelectric Switch 3-pin Compatible with Ar-duino Smart Car Robot - Arduino Uno REV3 [A000066] - AEDIKO 4 Sets TT Motor DC 3-6V Gearbox Motor Dual Shaft 200RPM Ratio 1:48 Motor with Tire Wheel Kit for Arduino DIY Smart Car Robot --- ## 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.tw/products/123955714-ir-infrared-obstacle-avoidance-sensor-2pcs-ir-transmitting-and-receiving](https://www.desertcart.tw/products/123955714-ir-infrared-obstacle-avoidance-sensor-2pcs-ir-transmitting-and-receiving) --- *Product available on Desertcart Taiwan* *Store origin: TW* *Last updated: 2026-07-07*
