The using of ZigBee protocol to organize the "Smart Home" system for aged people

Abstract

The machine-to-machine communication and automation are main trends in the world of modern infocommunications. The concept of Internet of Things is widely used for these purposes. It consists of two main categories namely long-range and short-range networks. The latter includes the "Smart Office" and "Smart Home" systems, which are very popular today. Various technologies enable the automation of processes such as security management, climate control, lighting, etc. This article will focus on the development of a "Smart Home" system for people with limited mobility using ZigBee technology. Basic and additional requirements needed in this system are specified. A brief description of the latest version of the ZigBee 3.0 protocol is provided. The software part of the considered ZigBee subsystem is based on the open-source code of the Zigbee2MQTT project, which supports integration with all common home automation services through the use of the standard MQTT protocol. Hardware part is presented. It includes both server and different types of smart devices. The recommendations for the implementation of some basic and optional requirements for the Smart Home system for an elderly person are given. Among them there is movement tracking, water leaks detection, lightning automation, SOS button, climate control, reminder of important things before leaving the house, television.
