MAKER-REFLECT

MAKER-REFLECT is an analogue reflectance sensor (line detector). It is an IR reflectance sensor module designed for reliable surface reflectivity detection in compact electronic and robotics applications. It provides an analogue voltage output that varies according to the amount of infrared light reflected from a surface, enabling accurate detection of light and dark contrasts. The sensor operates by emitting infrared light toward a target surface and measuring the reflected signal. It is optimized for close-range operation, with an optimal sensing distance of approximately 3 mm, making it suitable for applications requiring consistent and repeatable readings on flat surfaces.
