Fc 51 Ir Sensor Datasheet !!link!! File

Turn the potentiometer counter-clockwise until the indicator LED turns off, then test with an object.

This comprehensive guide serves as an expanded technical datasheet, explaining how the FC-51 works, its electrical specifications, pinout, adjustment procedures, and integration steps. Technical Specifications Fc 51 Ir Sensor Datasheet

The heart of the FC-51 module is the LM393 integrated circuit. This chip compares the analog voltage coming from the IR photodiode against a reference voltage set by the user. Because it handles the analog-to-digital translation on-board, your microcontroller does not need an Analog-to-Digital Converter (ADC) pin to read this sensor.
