Generic Photoelectric Infrared Count Slot Sensor Module 15mm Slot Width - LM393 Comparator Output
This 15mm slot-width photoelectric sensor module features an LM393 comparator for stable digital output, making it compatible with Arduino, Raspberry Pi, and other 3.3V/5V microcontrollers for object counting, speed detection, and position sensing applications.
Features
- 15mm optical slot width for object detection and counting
- LM393 comparator ensures clean, stable digital signal output
- Low-level active output (logic low when beam is broken)
- Wide 3.6V to 5V DC operating voltage range
- Compact 22mm x 20mm PCB footprint for easy integration

This photoelectric infrared slot sensor module operates on the beam-break principle, where an infrared transmitter and receiver are aligned across a 15mm gap. An object passing through the slot interrupts the beam, triggering a state change detected by the onboard LM393 voltage comparator. The comparator provides a debounced, digital output signal suitable for direct connection to microcontroller GPIO pins.
The module is designed for reliable operation in counting and speed measurement applications, featuring a fixed sensitivity optimized for general-purpose use. Its low active output simplifies code logic, and the dual LED indicators provide visual feedback on the sensor’s state (power and output). The compact design and standard 0.1″ pin spacing facilitate integration into prototypes and embedded systems.
