IoT Smart Home Controllers

Abstract

Smart home is a term that is commonly used to refer to homes where the appliances, light system, airconditioning, TVs etc. are capable of communicating with each other and can be controlled remotely according to a predefined schedule or via some kind of interface. This project presents a design and implements a smart controller compatible with IoT technology and standards to control home devices remotely such as (light system, water motor and curtain motor, etc.), connect the controller with smartphone via Ubidots standard application in IOS and Android compatible with IFTTT and Google Assistant. This controller can deal with multiple sensors and take one or more actions. The proposed system consists of two main components; the first part is the smart controller which can communicate with the server (Ubidots MQTT broker), which presents a system core that manages, controls, and monitors users home. Second part is the hardware interface module (application), which provides an appropriate interface to sensors and actuators of home systems. The application is used to communicate with the Ubidots database and update its values, this in turn enables us to control the various sensors and electrical appliances in the home. Unlike most of the available smart home systems in the market, the proposed system is scalable and one server can manage many hardware devices as long as it exists on WiFi network coverage. The proposed system is better from the scalability and flexibility point of view than the commercially available home automation systems
