DESIGN AND CONSTRUCTION OF AN AUTOMATIC LIGHT SENSOR SWITCH
Abstract
Abstract
The Automatic Light sensor switches to create an energy-efficient lighting system
that automatically activates when life but also contributes to energy conservation.
Through this project, we aim to demonstrate how simple, yet effective automation
solutions can be implemented using readily available components and an Arduino.
The surrounding light diminishes and turns off when there is sufficient light. It is
engineered to automate lighting is detected using the Passive infrared resistor
(PIR)sensor, removing the requirement for manual control, the lights convenient in
residential and commercial settings. This seamless process ensures that the light
turns on automatically, when necessary, thus reducing energy consumption. By
combining electronics and sensor control based on surrounding light conditions and
human presence, thereby enhancing energy efficiency and automatically in low-light
conditions with the help of light dependence resistor (LDR)if the presence of human
technology, the Automatic Light system using LDR and PIR sensor not only adds a
layer of convenience to daily microcontroller, paving the way for smarter, more
sustainable environments.
