2PCS FC-51 3-Pin IR Infrared Obstacle Avoidance Sensor Module for Arduino in Pakistan

The FC-51 IR Infrared Obstacle Avoidance Sensor Module (Pack of 2) is designed for obstacle detection in Arduino robot cars, robotics, and DIY electronics projects. It uses an infrared transmitter and receiver to detect reflected infrared light from nearby objects, helping robots respond to obstacles.

The module features an onboard adjustable potentiometer for changing detection sensitivity and distance. Its digital output allows easy connection to Arduino and other compatible microcontrollers. The three-pin interface makes wiring simple for beginners and electronics enthusiasts.

This sensor is suitable for obstacle-avoiding robots, robotic navigation experiments, object detection, and educational projects. It can also be used in certain line-following or surface-detection experiments, depending on the sensor arrangement and surface reflectivity.

Product Dimensions: Approximately 45 × 14 × 7 mm (Length × Width × Height), including the sensor assembly. The PCB size is approximately 31 × 14 mm. Measurements may vary slightly between manufacturers.

The FC-51 is a reflective infrared obstacle sensor, not a dedicated line-tracking sensor; its suitability for line-following depends on the project design.
