Fc 51 - Ir Sensor Datasheet [cracked]

Due to its fast response time and low power footprint, the FC-51 excels in several automated environments:

If the reflected signal is strong enough (meaning an object is close), the LM393 pulls the OUT pin LOW and turns on the obstacle LED. The Impact of Surface Properties

The sensor can be easily interfaced with microcontrollers like Arduino, Raspberry Pi, or other digital circuits. The output pin provides a digital signal that indicates the presence or absence of an object within the detection range. Fc 51 Ir Sensor Datasheet

If the reflected light is strong enough to pass the threshold, the LM393 pulls the OUT pin LOW and illuminates the green "Obstacle" LED. The Impact of Color and Material

An infrared LED that emits light at a specific wavelength (usually 940nm). Due to its fast response time and low

Note: This is a synthesized feature datasheet. For official specifications, refer to the FC-51 vendor datasheet or test with your specific board version, as clones vary.

Infrared light absorption varies by material color. Dark or black objects absorb IR light, significantly reducing the sensor's detection range. Conversely, white or reflective surfaces maximize the range. If the reflected light is strong enough to

The FC-51 module features a simple 3-pin interface header, making it exceptionally easy to connect to breadboards or microcontroller development boards. Pin Number Description Input Power Supply (3.3V - 5V DC) GND Ground Reference (0V) OUT Digital Output (Active LOW) Onboard Hardware Components

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

The infrared emitting tube continuously shoots out a beam of high-frequency infrared light.
