OSOYOO Tracking sensor module
The OSOYOO IR Track Sensor is essentially a combination of IR LED and IR detector which can be used to detect black and white colors. It works by sending a beam of IR light from IR LED toward the surface. The IR detector will get the reflection signal from surface and judge if the surface is white or black color.
