Fc 51 Ir Sensor Datasheet

Clockwise rotation increases detection distance; counter-clockwise decreases it. How the FC-51 Sensor Works

The module operates based on . An onboard IR LED (the transparent transmitter) continuously emits infrared light. When an object enters the detection range, the light bounces off the object's surface and is captured by the IR receiver (the black photodiode). Go to product viewer dialog for this item.

Do not force the potentiometer past its stops. Adjust only ±270 degrees typically. Fc 51 Ir Sensor Datasheet

Detects reflected infrared light.

The FC-51 is a low-cost, highly efficient infrared (IR) obstacle avoidance sensor widely used in robotics, automation, and DIY electronics. It features an onboard IR transmitter and receiver pair that detects objects within a specific range. When an object enters the detection range, the

| Pin Number | Name | Function | | :--- | :--- | :--- | | 1 | | Digital output signal (HIGH = no object, LOW = object detected) | | 2 | VCC | Power supply input (3.3V or 5V) | | 3 | GND | Ground (0V) |

The FC-51's 3.3V compatibility makes it a great choice for the Raspberry Pi ecosystem. Adjust only ±270 degrees typically

The FC-51 uses logic. This is crucial for programming.
