Fc 51 Ir Sensor Datasheet

The compact design and male headers make it ideal for quick breadboarding. 5. Applications The FC-51 sensor is commonly used in: Robotics: Obstacle avoidance for robots. Automation: Proximity switches and object counters.

Obstacle avoidance for wheeled or tracked mobile robots.

Sunlight and incandescent bulbs emit massive amounts of infrared light, which can blind or saturate the IR receiver. The compact design and male headers make it

The is a powerful yet simple tool for proximity and object detection. While it may lack the precision of a laser or the range of an ultrasonic sensor, its low cost, ease of use, and reliable digital output make it an ideal choice for thousands of hobbyist and educational projects.

If the sensor output flickers or fails to trigger, use a small screwdriver to adjust the onboard potentiometer until the Obstacle LED reliably responds to your target object. Automation: Proximity switches and object counters

Scenario B: The Sensor does not detect objects at close range
