About this item

The DFRobot Gravity: Infrared Light Photo Interrupter Module (940nm) is a compact and precise sensor designed for detecting object presence by interrupting an infrared light beam. Utilizing the ITR9608 slotted photoelectric switch, it offers high sensitivity and accuracy. With a 5.0mm photonic gap, it can detect objects of various sizes, making it versatile for applications such as object counting, speed detection, smart card switches, and printer paper detection. The module operates within a voltage range of 3.3V to 5.5V and provides a digital output signal. Its standard Gravity interface ensures easy integration with platforms like Arduino, micro:bit, and UNIHIKER. The module's compact dimensions (27x32mm) and lightweight design (4g) make it suitable for space-constrained projects.
