Operating at 3.3V-5V DC, it offers adjustable detection distances from 2 to 60 cm with a 35° detection angle. Its TTL output directly interfaces with microcontrollers or drives relays and buzzers, making it a versatile and reliable choice for precise obstacle detection and line tracking in professional and DIY applications. ## Description Description: This module provides a versatile infrared detection system solutions for automation machinery devices such as smart cars, robots. The sensor module is adaptable to ambient light. It has a pair of infrared transmitting and receiving tube. Transmitting tube sends out a certain frequency IR which will be reflected when detecting obstacles (reflecting surface) and received by receiving tube. After processing with comparator circuit, output interface outputs digital (a low voltage level signal). Specifications: Working Voltage: 3.3V-5V DC Working Current: >1A Detection Distance: 2~60cm Detection Angle: 35° Size: Big Board: 42*38*12mm Small Board: 25*12*12mm Mounting Hole Diameter: 3mm Note: 1, Do not put probe toward sunlight. Sunlight will cause interference to module. 2, Sensitivity should not be regulated excessively high because high sensitivity can easily lead to false trigger. Package Includes: 1 x Infrared Tracking Module Set ## Features - When the module detects obstacles signal, red indicator lights on and OUT port continuous outputs low voltage level at the same time - Detection distance can be adjusted with potentiometer, clockwise to increase and counterclockwise to reduce - Target reflectivity and shape is the key point of detection distance. Small and black objects have minimum detection distance, while large and white ones have maximum distance - Output port can be directly connected to the SCM IO port, also can drive a 5V relay module or buzzer module directly - Widely used in robot obstacle avoidance, car obstacle avoidance, assembly line counting and black white line tracking ## Technical Specifications | Specification | Value | |---------------|-------| | Manufacturer | Fdit | | Part number | Zunaten3rdfgg91s | | Item Weight | 22 g | | Product Dimensions | 4.2 x 3.8 x 1.2 cm; 22 g | | Manufacturer reference | Zunaten3rdfgg91s | | Item Package Quantity | 1 | | Batteries included? | No | | Batteries Required? | No | ## Images ![Infrared Obstacle Avoidance Sensor Module, IR 4-channel Tracking Sensor Module, DC 3.3V-5V TTL Smart Car PCB for Science Project - Image 1](https://m.media-amazon.com/images/I/71M+UZ5JSVL.jpg) ![Infrared Obstacle Avoidance Sensor Module, IR 4-channel Tracking Sensor Module, DC 3.3V-5V TTL Smart Car PCB for Science Project - Image 2](https://m.media-amazon.com/images/I/71HdDGkc6SL.jpg) ![Infrared Obstacle Avoidance Sensor Module, IR 4-channel Tracking Sensor Module, DC 3.3V-5V TTL Smart Car PCB for Science Project - Image 3](https://m.media-amazon.com/images/I/71t5WNi63uL.jpg) ![Infrared Obstacle Avoidance Sensor Module, IR 4-channel Tracking Sensor Module, DC 3.3V-5V TTL Smart Car PCB for Science Project - Image 4](https://m.media-amazon.com/images/I/71HULdPmbyL.jpg) ![Infrared Obstacle Avoidance Sensor Module, IR 4-channel Tracking Sensor Module, DC 3.3V-5V TTL Smart Car PCB for Science Project - Image 5](https://m.media-amazon.com/images/I/61fCirj5ulL.jpg) --- ## 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.com.my/products/232129166-infrared-obstacle-avoidance-sensor-module-ir-4-channel-tracking-sensor](https://www.desertcart.com.my/products/232129166-infrared-obstacle-avoidance-sensor-module-ir-4-channel-tracking-sensor) --- *Product available on Desertcart Malaysia* *Store origin: MY* *Last updated: 2026-11-15*
