Fc 51 Ir Sensor Datasheet Hot ((install)) Jun 2026

Working on an obstacle avoidance robot or a line follower? The FC-51 Infrared Obstacle Avoidance Sensor is a staple for Arduino and ESP32 projects. If you are looking for the specs, pinouts, and technical details to get your build moving, check out the datasheet below.

Digital TTL level (Low/0V when an obstacle is detected, High/VCC when the path is clear)

The FC-51 is a low-cost, versatile infrared (IR) obstacle avoidance sensor module widely used in robotics and automation projects. It is designed to detect objects at short distances without physical contact. Commonly utilized in line-following robots, obstacle-avoiding vehicles, and interactive installation art, the FC-51 offers a simple digital output that makes it easy to interface with microcontrollers like Arduino, ESP32, and Raspberry Pi. fc 51 ir sensor datasheet hot

Lead engineer, Rachel, furrowed her brow as she pored over the FC-51 datasheet, searching for any clues that might explain the sensor's erratic behavior. She noticed that the datasheet specified a maximum operating temperature of 50°C (122°F), but the ambient temperature in the lab was already pushing 35°C (95°F).

: When an obstacle is in front of the sensor, the OUT pin goes LOW, the built-in LED on pin 13 lights up, and you see "Obstacle detected!" in the Serial Monitor. Working on an obstacle avoidance robot or a line follower
