An IoT-based appliance control system for smart homes

TLDR

The growing number of household appliances creates a need for efficient, convenient management to enhance comfort, security, and health in homes. This paper proposes an IoT-based smart control system to address efficient appliance management. The system employs a 433 MHz wireless sensor and actuator network controlled by a central hub, with modular switch and RF control units, and interfaces via Wi‑Fi to client devices, enabling easy addition or removal of appliances and providing monitoring, control, security, and energy analytics. The proposed system solves the appliance management problem.

Abstract

With the development of the social economy, more and more appliances have been presented in a house. It comes out a problem that how to manage and control these increasing various appliances efficiently and conveniently so as to achieve more comfortable, security and healthy space at home. In this paper, a smart control system base on the technologies of internet of things has been proposed to solve the above problem. The smart home control system uses a smart central controller to set up a radio frequency 433 MHz wireless sensor and actuator network (WSAN). A series of control modules, such as switch modules, radio frequency control modules, have been developed in the WSAN to control directly all kinds of home appliances. Application servers, client computers, tablets or smart phones can communicate with the smart central controller through a wireless router via a Wi-Fi interface. Since it has WSAN as the lower control layer, a appliance can be added into or withdrawn from the control system very easily. The smart control system embraces the functions of appliance monitor, control and management, home security, energy statistics and analysis.
