Fc 51 Ir Sensor Datasheet

Connecting the FC-51 sensor to an Arduino is straightforward. FC-51 VCC -> Arduino 5V FC-51 GND -> Arduino GND FC-51 OUT -> Arduino Pin 2 Simple Arduino Code:

The FC-51 module is designed for simplicity and low power consumption. Below are the absolute maximum ratings and typical operating characteristics. Electrical Characteristics 3.3V to 5V DC Operating Current: ≥is greater than or equal to

*Note: The EN (Enable) pin is rarely populated on standard breakout boards; usually, the sensor is always enabled. Fc 51 Ir Sensor Datasheet

Positioned across conveyor belts to count passing items as they break the IR beam.

print('Checking for obstacles...') while True: if sensor.value() == 0: print('Obstacle detected!') switching() # Debounce: Wait until the sensor is clear again while True: time.sleep(0.5) if sensor.value() == 1: break time.sleep(0.1)

| Parameter | Value | | :--- | :--- | | | 3.3V – 5V DC | | Current Consumption | Approx. 20mA – 30mA | | Detection Distance | 2cm to 30cm (Adjustable) | | IO Interface | 4-pin (VCC, GND, OUT, EN*) | | Output Signal | Digital (TTL Low when object detected) | | Sensor Chip | LM393 Comparator | | IR Wavelength | 950 nm | | Effective Angle | Approx. 35° | | Dimensions | Approx. 32mm x 14mm | | Operating Temperature | 0°C to +50°C | Electrical Characteristics 3

Decreases the detection distance threshold.

Choose FC-51 for simple “object present/not present” binary detection from 2-30 cm. Avoid for distance measurement or shiny/black objects.
