FC-51 IR Infrared Obstacle Avoidance Sensor Module
Key Features
Model: IR Obstacle Avoidance Sensor Module
Detection Principle: Infrared Emitter & Photodiode Pair
Operating Voltage: 3.3V to 5V DC
Output Format: Digital High/Low signal (0 or 1)
Adjustment Interface: Onboard potentiometer for range tuning
The IR Sensor module provides simple obstacle detection for automated builds. It bounces a beam of invisible infrared light off nearby surfaces; if the onboard receiver captures the reflection, it flips its digital output pin to alert the microcontroller.
