Fc 51 Ir Sensor Datasheet

A voltage comparator chip that processes the signal from the receiver to determine if an object is present.

: Acts as a simple "tripwire" for entry detection.

When the object is near the threshold distance, the output can oscillate between HIGH and LOW, as noted in experimental testing. To mitigate this, implement software debouncing (e.g., require multiple consistent readings before triggering) or hysteresis in your code.

The LM393 voltage comparator compares the voltage from the photodiode against a reference voltage set by the potentiometer. A voltage comparator chip that processes the signal

Absorb IR light. A matte black object may need to be significantly closer to the sensor to trigger a detection, a characteristic often exploited in line-following robots. Arduino Interfacing Guide

All crucial technical parameters are compiled in the table below. This data, compiled from various sources, serves as a reliable reference for engineers and hobbyists integrating the FC-51 into projects. When the object is near the threshold distance,

int sensorPin = 2; int ledPin = 13; int sensorState = 0;

If no obstacle is present, the light radiates outward and dissipates. When an object passes in front of the sensor, the IR light bounces off the object's surface.

Positioned across a conveyor belt to count items as they break the IR beam.

The module features a small, single-turn potentiometer (trimpot) located on the PCB.
