KY-010 Slot Light Sensor Module (PHOTO INTERRUPTER)

The KY-010 Slot Light Sensor Module (PHOTO INTERRUPTER) EM-AB037 is an ideal choice for your Arduino and other microcontroller projects. This sensor is designed to detect objects passing through a slot, consisting of an infrared (IR) LED and a phototransistor. Its main working principle is to detect the presence or absence of an object in the slot; when an object passes, the IR beam is interrupted, and the output of the phototransistor changes. Thanks to this feature, the KY-010 is widely used in speed measurement, position determination, counting systems, robot navigation, and various DIY electronics projects. For example, it is a perfect sensor for tracking the rotation of a robot's wheel or counting objects in an automated system. This reliable sensor is an indispensable component for electronics enthusiasts and engineers.
