IoT Based Security and Controlled Smart Home Automation System Using GSM

Abstract

Now-a-days, technology has overcome the basic daily problems of human beings, which is mainly reduced to an extent by approaching of IOT, further developed the system more upgraded, systematic and effective. The design challenges in home automation are increasingly apparent but, providing the platform for controlling home appliances, their monitoring, programming and simultaneously preventing the entrance of any intruder into the house thereby maintaining security by improvising the system with electronic door lock arrangement. Thus, this system fulfills the essential need of developing a fully independent and extensible home system that can support devices and technologies of differing functionalities and protocols. In this paper, we present a home automation system using Arduino MEGA microcontroller and GSM SIM900 as a connectivity module. It helps the user to manage various appliances such as light, fan, TV and can take decision based on the feedback of sensors remotely. It also helps to provide notification on the Android app by turning its indication from ‘’green’’ to ‘’red’’ intimating about the danger is about to happen in the house. Also, automatically switched OFF the appliances or stopping the flow of water from water tap after noticing programmed period of time. Additionally, it allows the person to enter in the house who have authenticated RFID only, thereby if any intruder tries to enter by displacing door, it will provide the notification on the App. We have tested our system through conducted experiment on various environmental conditions.
