3-Channel IR Line Tracking & Path Detection Sensor Module

The 3 Channel Path Tracing Module is a reflective infrared sensor module designed for line following, path detection, and edge sensing applications. Equipped with three independent IR emitter–receiver pairs, it can accurately detect black/white contrast and guide robots or automated vehicles along a predefined path. The module provides stable digital outputs and is ideal for robotics competitions, DIY robots, educational STEM projects, and automation systems requiring multi-point line tracking.Features:3 independent IR sensing channels for accurate path detectionStable digital output signals for easy microcontroller interfacingHigh sensitivity to black/white surface contrastAdjustable detection threshold (potentiometer, on compatible versions)Suitable for line-following robots and automated guided systemsCompact and lightweight PCB designCompatible with Arduino, ESP32, Raspberry Pi, and robotic controllersSpecifications:Sensor Type: IR reflective sensors (3-channel)Output Type: Digital (HIGH/LOW for each channel)Operating Voltage: 3.3V – 5VDetection Range: Typically 0.5 – 3 cm (surface dependent)Sensitivity: Adjustable (versions with onboard potentiometers)Indicators: Onboard signal LEDs for each channelInterface: 3 digital outputs + VCC + GNDDimensions: Compact module sizeApplications: Line-following robots, path tracing, edge detection, AGV systems, DIY roboticsPackage Includes:1 × 3-Channel IR Line Tracking & Path Detection Sensor Module
