KY-010 Light break sensor module

Photo Interrupter Module Keyes KY-010 for Arduino, will trigger a signal when light between the sensor’s gap is blocked.

The KY-010 Photo Interrupter module consists of an optical emitter/detector in the front and two resistors (1 kΩ and 33 Ω) in the back. The sensor uses a beam of light between the emitter and detector to check if the path between both is being blocked by an opaque object.

Operating Voltage 3.3 ~ 5V
