Wireless Home Automation System Using IoT and PaaS

Home automation based on Internet of Things (IoT) is getting huge attention of mass people in recent years. Smart home eases and secures the management of the home appliances. This paper presents a low cost and reliable smart home system that assists the users to manage home appliances without the need of their physical presence. The proposed system includes smart door lock system using Radio Frequency Identification (RFID) card and password. It can store and display information of temperature & humidity of a home, and notifies the users of switching on/off time of light, fan and other home appliances using embedded micro-web server and an IoT platform. The user can also control the light intensity and fan speed based on LDR and temperature sensor values respectively. The system includes gas leakage & fire alarm. It has leakage gas removing & fire extinguishing facility and SMS notification system using IoT platform. The system uses real IP and RESTful API for controlling, monitoring and accessing the home appliances remotely from anywhere in the world using Android based smartphone app or web app. This system is user friendly and energy efficient.
