KY-010 Photo Interrupter Module for Arduino will trigger a signal when light between the sensor's gap is blocked.
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 de emitter an detector to check if the path between both is being blocked by an opaque object.
Package Includes:
1 x KY-010 Photo Interrupter Module
