Broken Light Module Digital Sensor – Light Shield Interruption Detector with LED

The Broken Light Module Digital Sensor is a simple yet powerful light interruption detection module designed for use in automation, robotics, and DIY Arduino projects. It detects when an object breaks the path of light between its built-in infrared emitter and detector, triggering a digital signal output.

This module is ideal for light-shield warning systems and photo-interruption logic where a beam break indicates motion or blockage. The built-in LED tied to Arduino’s digital interface pin 13 responds based on sensor output, providing an instant visual indicator. With only a few components—an optical sensor and onboard resistors—this module offers an easy-to-use platform for obstacle detection and event-triggered responses.
