Obstacle Sensor Module

The Obstacle Sensor Module is an infrared (IR) based proximity detection module designed to detect nearby objects without any physical contact. It works by emitting infrared light from an IR transmitter and detecting the reflected signal using an IR receiver. When an obstacle is detected within its range, the module provides a digital output signal, making it suitable for use in automated and robotic systems.

This module is widely used in robotics and embedded applications for obstacle avoidance, object detection, and motion-based control systems. It is commonly integrated into robotic vehicles and smart automation projects where real-time detection of nearby objects is required.

The detection range of the module can be adjusted using an onboard potentiometer, allowing users to fine-tune sensitivity based on application requirements. It provides a simple digital output (HIGH/LOW) that can be directly interfaced with microcontrollers such as Arduino, ESP8266, ESP32, and Raspberry Pi. An onboard LED indicator helps visually confirm obstacle detection.
