Abstract:

Undoubtedly, energy crisis is one of the most important challenges in this century for the world and hence energy optimization is the best feasible alternative that is economically possible. The present work offers simple solution for automation of electrical appliances so that energy can be optimized with manual back up. Automation is provided with the use of various sensors suitable to observe the production processes, actuators and different techniques and devices. In this project, the automation system developed in a smart room are: automatic 220V lamp control using LDR, automatic lamp control using LDR and PIR sensor, automatic fan control using DHT11 sensor, and automatic load control using ac dimmer circuit. In all these applications, Arduino UNO processing- unit along with 3 sensors and a dimmer circuit. This system is designed to control electrical devices throughout the house with ease of installing it, ease of use and cost effective design and implementation, reduction in energy power wastage and hence resulting in lowered electricity bills, due to optimal use of electrical energy with adaptation.
