A KY-010 is a photo interrupter module or a light barrier that notices a light beam whenever it is blocked through an object and sends a signal whenever the interruption happens; this module is used commonly in different Arduino projects so that it detects the presence or movement of. The signal pin will go high when an object blocks light from passing between its emitter and detector. It's ideal for applications requiring non-contact object detection, such as counting or speed measurement.
