IR Sensor Module – Infrared Obstacle Detection for Arduino and Robotics
The IR Sensor Module is a compact and easy-to-use infrared sensor for obstacle detection, line following, and proximity sensing. It works by emitting infrared light and detecting the reflection from nearby objects. Ideal for robotics, automation, and DIY electronics projects, this module is highly compatible with Arduino, Raspberry Pi, and other development boards.
 
Key Features:
Infrared Obstacle Detection
Detects objects within a short range using IR reflection—ideal for line-following and edge detection.
Adjustable Sensitivity
Onboard potentiometer lets you fine-tune the detection range for various applications.
Digital Output
Outputs HIGH or LOW based on object proximity—easy to interface with microcontrollers.
Onboard Indicators
Built-in power and signal LEDs for easy status monitoring and debugging.
Plug-and-Play
Simple 3-pin interface: VCC, GND, OUT—no complicated setup required.
 
Applications:
Line-following and obstacle-avoiding robots
Automatic lighting and proximity alerts
Object detection in automation systems
DIY electronics and sensor-based projects
Entry/exit detection for small enclosures
