The KY-010 Photo Interrupter module is a switch that will trigger a signal when light between the sensor’s gap is blocked.
This module is suitable for various electronics platforms like Arduino, Raspberry Pi, ESP32 and others.
KY-010 SPECIFICATIONS
This module consists of an optical emitter/detector and 3 male header pins on the front. On the back there are two resistors of 1kΩ and 33Ω.
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.
