IR Break Beam Infrared Photoelectric Proximity Sensor, 1M Detection Distance, NPN Normally Open Output, DC 5V, Compatible with Arduino, STM32, PLC and 51 Microcontrollers

Product Overview
This IR break beam sensor is a photoelectric proximity switch that detects the presence or absence of objects. It uses a beam of light and a synchronous circuit to sense when the beam is blocked or reflected. Objects are not limited to metals, so all reflective objects can be detected. It offers high sensitivity, fast response speed, and good stability, and it responds faster than PIR sensors, giving you better control over exactly where motion is detected.
