A compact infrared reflection sensor module that detects objects by measuring reflected light from its own IR LED. Designed for reliable, easy integration in hobby and industrial projects. - Power and compatibility: Supply voltage 2.5-12 V (do not exceed 12 V). Current at 5 V typically 18-20 mA. Simple to drive with most microcontrollers; outputs can feed standard digital inputs. - Easy installation: Fixed screw holes for secure mounting on panels, brackets, or PCBs. - Sensing principle: Detects reflected infrared light to determine presence or proximity of a target without contact. - Adjustable sensitivity: Multi-turn precision potentiometer to set the detection threshold. - Performance: Low power consumption, compact form factor, stable operation across the specified voltage range. - Applications: - Obstacle detection for small robots or line-following robots - Presence or proximity sensing on conveyors, shelves, or packaging lines - Door or access sensing in vending machines or automation systems
