MOTION ACTIVATED PATHWAY LIGHTENING SYSTEM

Abstract: The Motion Activated Pathway Lighting System is a smart lighting solution designed to enhance energy efficiency and safety in both public and private environments. The system automatically activates pathway lights when motion is detected and turns them off after a predefined time of inactivity. It primarily uses IR (Infrared) or PIR (Passive Infrared) sensors to detect movement and an LDR (Light Dependent Resistor) to ensure operation only in low-light conditions, such as during nighttime. The core control unit of the system is based on the Arduino Mega 2560, which processes sensor data and controls the LED lights via a relay module. This system also includes a dimmer function that allows for a gradual fade-in and fade-out of the lights, improving user comfort and extending the lifespan of the LEDs. The entire setup is powered using a rechargeable lithium battery supported by a step-up voltage converter, making it suitable for remote or outdoor installations. Additional components such as heat sinks and cooling fans ensure the stability of the system. The project is ideal for application in residential complexes, parks, parking areas, industrial zones, and institutional campuses where intelligent lighting control can reduce energy usage and improve user experience.
