## Description

The Line Trace Sensor Module uses an infrared emitter/detector pair to measure the reflectivity of a surface below it. When the reflectivity exceeds an adjustable threshold, the output goes low — making it ideal for building line-following robots and edge-detection systems. The onboard potentiometer lets you fine-tune the detection threshold to suit different surfaces and lighting conditions. Compatible with Arduino and other microcontrollers operating at 2.5–12V. Key Features IR Reflectivity Sensing – Detects surface reflectivity changes for line tracking Adjustable Threshold – Onboard potentiometer for fine-tuning sensitivity Active Low Output – Output goes low when reflectivity exceeds threshold Wide Voltage Range – 2.5–12V power supply for broad compatibility Simple 3-Pin Interface – VCC, OUT, and GND for easy wiring Specifications Output Signal – Active low (TTL level) Interface – 3-pin (VCC / OUT / GND) Power Supply – 2.5–12V Working Current – 18–20mA at 5V Ideal For Line-following robots Edge detection and table-edge avoidance Surface reflectivity measurement Arduino and microcontroller beginner projects Package Contents 1× Line trace sensor module
