If the reflection is strong enough (meaning an object is close), the module drives its digital output pin ( OUT ) LOW (0V) and illuminates the onboard obstacle indicator LED. If no obstacle is present, the output remains HIGH (VCC) . 2. Technical Specifications Specification Value Operating Voltage (VCC) 3.3V to 5V DC Operating Current ≥is greater than or equal to Output Type

Counts items moving down a factory line as they interrupt the IR beam. GND: Ground Reference

When an object enters the sensor's field of view, the emitted infrared light reflects off the object's surface back toward the sensor.

The FC-51 IR sensor is a reflective infrared sensor that can detect the presence of objects within a certain range. It is commonly used for obstacle detection, line following, and other applications.
