{"title":"Arduino Line Trace Sensor Module","handle":"arduino-line-trace-sensor-module","url":"/products/arduino-line-trace-sensor-module","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.\n\nThe 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.\n\nKey Features\n\n\nIR Reflectivity Sensing – Detects surface reflectivity changes for line tracking\n\nAdjustable Threshold – Onboard potentiometer for fine-tuning sensitivity\n\nActive Low Output – Output goes low when reflectivity exceeds threshold\n\nWide Voltage Range – 2.5–12V power supply for broad compatibility\n\nSimple 3-Pin Interface – VCC, OUT, and GND for easy wiring\n\n\nSpecifications\n\n\nOutput Signal – Active low (TTL level)\n\nInterface – 3-pin (VCC / OUT / GND)\n\nPower Supply – 2.5–12V\n\nWorking Current – 18–20mA at 5V\n\n\nIdeal For\n\nLine-following robots\nEdge detection and table-edge avoidance\nSurface reflectivity measurement\nArduino and microcontroller beginner projects\n\n\nPackage Contents\n\n1× Line trace sensor module\n","vendor":"Little Bird","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":5902,"title":"Default Title","sku":"LB-LR0005","price":6.82,"on_sale":false,"in_stock":true,"available_quantity":126,"option1":"Default Title"}]}
