Correlation Photoelectric Infrared Count Slot Sensor Module – 15mm

The Correlation Photoelectric Infrared Count Slot Sensor Module 15 mm is a reliable and cost-effective optical sensing solution designed for object detection, motor speed measurement, and industrial counting applications. With a wide 15mm infrared slot and LM393 comparator chip, this sensor ensures accurate and stable pulse detection for microcontroller-based systems like Arduino and Raspberry Pi.

When no object is present in the slot, the red LED lights up and the OUT pin outputs a low signal. When an object interrupts the beam, the OUT pin outputs a high signal, and the red LED turns off—making it extremely simple to use in counting, rotation sensing, and position monitoring. This module is ideal for projects that require accurate detection with minimal code.

Note: Sensitivity is fixed and cannot be adjusted. The module has a compact form factor and includes a signal indicator LED and pre-configured output circuitry.
