Connect GND to system ground.Digital output: Connect the module’s OUT pin to a digital input pin on your microcontroller. The module outputs a logic high or low based on detection.Example: Arduino WiringVCC -> 5V (or 3.3V if using 3.3V systems)GND -> GNDOUT -> Digital input D2 (or any digital pin)Example: Raspberry Pi WiringVCC -> 3.3V (recommended to avoid damaging Pi GPIO if module uses 3.3V logic)GND -> GNDOUT -> GPIO input pin (use a pull-up or pull-down in software as needed)Quick Start GuideMount the sensor module on your robot chassis using the provided mounting holes at a suitable height from the ground.Wire VCC, GND, and OUT to your controller following the wiring examples above.Power up your controller and read the OUT pin in your sketch or script; the output will change state when a line or obstacle is detected.Adjust the onboard potentiometer while testing to set the sensitivity for your surface and ambient light conditions.Test in real conditions and fine-tune mounting and sensitivity for reliable operation.Mounting and Adjustment TipsKeep the sensor close to the surface for line detection but high enough to avoid debris and uneven terrain.Adjust sensitivity in small increments while testing to prevent false triggers from ambient light or reflections.For multi-sensor arrays (line followers), space sensors evenly and calibrate each sensor individually.Use shielding or a small skirt around the sensor for improved performance in bright ambient light.Why Choose This IR Sensor ModuleThis IR Infrared Obstacle Avoidance-Line Follower Sensor Module offers a practical combination of reliability, adjustability, and easy integration. It is an excellent choice for hobbyists, educators, and professionals building robots, AGVs, or automation systems that require compact, cost-effective obstacle detection and line tracking.NoteImages are for illustration purposes only.
