A Multifarious Design of a Microcontroller Based Home Security and Automation System

This research aims to provide low cost, efficient automation and security system for home by using Arduino. Home automation means controlling the activities of home appliances and features automatically in a predetermined technique. It initially involves the control and automation of systems that ensure human comforts such as lighting, fire extinguisher, air conditioning, and security. This smart technology helps to get desired security and brings comfort in daily life. Commercial home automation systems are still not affordable for middle -class families in developing countries. Thankfully, with the availability of cheap microcontrollers, like Arduino, it has enabled an easy implementation of low-cost home automation systems including all the features those are added to those high end and commercial devices for home automation and security management. In this paper, we present a simple, low cost and multi-functional home automation system based on Arduino microcontroller. The whole system can be operated with the help various effective sensors which detect problems and on the other hand, takes a step to fix them. This project also includes a Bluetooth module and Arduino Bluetooth controller application with which the functions are executed.
