Fc 51 Ir Sensor Datasheet ^new^ -

The FC-51 IR Obstacle Avoidance Sensor is a popular and cost-effective module used widely in robotics for proximity detection and obstacle avoidance. It operates on the principle of infrared (IR) light reflection, utilizing an IR emitter and receiver pair alongside an LM393 comparator to provide a simple digital output.

Environmental Interference: Performance can be inconsistent under strong ambient light or sunlight, which may require shielding or recalibration of the sensitivity potentiometer. The FC-51 IR Obstacle Avoidance Sensor is a

Detection: The phototransistor receives the reflected light, and the onboard comparator compares this signal against the threshold set by the potentiometer. Operating Voltage : 3
