Generic Photoelectric Infrared Count Slot Sensor Module 10mm Slot Width - LM393 Comparator Output
This photoelectric infrared slot sensor module provides a digital output via an LM393 comparator for counting objects or measuring rotational speed. It is compatible with 3.6-5V microcontrollers like Arduino, Raspberry Pi, and ESP32 for integration into automation and monitoring systems.
Features
- 10mm wide optical coupling slot for object detection
- Digital output via LM393 comparator (active-low logic)
- Wide 3.6V to 5V DC operating voltage range
- Dual LED indicators for power and output status
- Compact PCB design for easy integration into projects

This module utilizes an infrared transmitter and receiver pair aligned across a 10mm wide slot. When an object passes through the slot, it interrupts the IR beam, causing the onboard LM393 comparator to switch its output state. The output is configured as active-low, providing a clean digital signal suitable for direct connection to microcontroller GPIO pins.
Designed for reliability in counting and speed measurement applications, the module features a fixed sensitivity and stable performance across its specified voltage range. Its compact form factor and simple interface make it ideal for integration into DIY electronics, educational robotics, and light industrial automation tasks where non-contact object detection is required.
