IR Infrared Obstacle Avoidance Sensor
The IR Infrared Obstacle Avoidance Sensor is a compact and reliable sensor module that uses an infrared emitting LED and a phototransistor to detect objects within a short-range proximity. When an object is in front of the sensor, the emitted IR light reflects off the surface and is detected by the receiving sensor, triggering an output signal.
This module is widely used in robotics, automation systems, and security applications where obstacle detection is required. It works with microcontrollers like Arduino, ESP32, Raspberry Pi, and other embedded systems.
The adjustable detection range and high response speed make it ideal for collision avoidance in robots, automatic doors, line-following robots, and interactive projects.
Key Features:
✅ IR Transmitter & Receiver Module – Uses infrared reflection for obstacle detection.
✅ Adjustable Sensitivity – Detects objects from a short distance (2-30 cm, depending on surface).
✅ Fast Response Time – Quick obstacle detection for real-time applications.
✅ Compatible with Microcontrollers – Works with Arduino, ESP32, Raspberry Pi, and other MCUs.
✅ Low Power Consumption – Ideal for battery-powered projects.
✅ Easy to Interface – Provides a digital output signal (HIGH/LOW).
✅ Compact and Lightweight – Perfect for robotic and embedded applications.
This infrared sensor module is an essential tool for robotics and automation, allowing devices to sense and avoid obstacles efficiently.
