Arduino Line Trace Sensor Module
We have ✅ 126 available of the LB-LR0005 in our Sydney warehouse.
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.
