Datasheet — Fc 51 Ir Sensor

Turn the potentiometer counter-clockwise until the indicator LED turns off, then test with an object.

The FC-51’s 3.3V to 5V compatibility makes it an easy match for most platforms.

Here are some example code snippets to quickly get the FC-51 up and running. Fc 51 Ir Sensor Datasheet

is a popular infrared (IR) obstacle avoidance sensor module commonly used in robotics for object detection and line tracking Inforbatista

Illuminates when the module is correctly powered. is a popular infrared (IR) obstacle avoidance sensor

Direct sunlight or strong fluorescent lighting can saturate the IR receiver, causing false triggers. Avoid using this sensor in bright outdoor environments.

Digital TTL (Low level when an obstacle is detected, High level when clear) Onboard Comparator: LM393 chip for stable signal processing Dimensions: 32mm × 14mm Digital TTL (Low level when an obstacle is

Adjustable from 2cm to 30cm (some variants reach up to 80cm). Detection Angle: Approximately 35°.
