DFRobot Gravity light barrier module / limit switch

The Gravity: Infrared Light Photo Interrupter Module integrates a powerful ITR9608 photoelectric switch. With its compact design and ease of use, it is the ideal choice for electronic projects and applications. This module provides precise photoelectric detection and efficient signal processing for robots, automation devices, and counting systems. The photo interrupter works by blocking light with an object, with a light emitter and a light receiver positioned opposite each other. When an object interrupts the light path, the light is blocked at the receiver, which triggers the operation of the sensor.

Features:
The sensor offers high sensitivity and precision through the use of the ITR9608 photoelectric switch. A wide phototonic gap of 5.0 mm enables the detection of objects of different sizes. Simple and user-friendly operation thanks to the standard gravity interface. Strong compatibility with Arduino, micro:bit, and UNIHIKER, offering a wide range of applications. Fast response time enables immediate detection of object entry or exit.

Application examples:
Object counting on production lines. Speed measurement by detecting intermittent interruptions of rotating components. Smart card switches for detecting the insertion and removal of cards, e.g., in hotel rooms to control the power supply. Paper recognition in printers and copiers to control printing and transfer processes. Automatic sensor technology in vending machines and small household appliances.
