Obstacle Avoidance Sensor Module for Arduino
Obstacle Avoidance Sensor Module for arduino is an infrared-based detection device designed to identify nearby objects and enable responsive behavior in electronic systems.
This module uses infrared (IR) transmission and reception to detect obstacles within a short range. When an object is detected, the sensor outputs a digital signal that can be processed by microcontrollers such as Arduino, ESP32, or Raspberry Pi.
The module features an adjustable sensitivity potentiometer, allowing users to control detection distance and optimize performance for different environments. It is commonly used in robotics, automation, and embedded system projects where object detection is required.
