Fc 51 Ir Sensor Datasheet Hot May 2026

A small screw on the potentiometer allows you to fine-tune the range.

The FC-51 is a compact, low-cost infrared obstacle avoidance sensor, typically featuring a comparator (LM393) with an adjustable potentiometer for range detection (approx. 2cm to 30cm). While often used in robotics, its principles are seamlessly integrated into modern lifestyle and entertainment systems. fc 51 ir sensor datasheet hot

Place the FC-51 inside a dark drawer or wardrobe. The moment you open it, the sensor detects the change in reflection (or your hand reaching in) and turns on an LED strip. No more fumbling for clothes in the dark. A small screw on the potentiometer allows you

The module features a small blue potentiometer. Rotating this screw adjusts the threshold voltage. low-cost infrared obstacle avoidance sensor
