The Designing and Implementation of a Smart Home System with Wireless Sensor/Actuator and Smartphone

This paper presents the design and implementation of a prototype system that employs standing techniques for smart home sensing and control for a future home environment. Smartphones currently show great potential in sensing, processing and communication capabilities. The prototype provides solutions for communications between home users, electronic equipment and a Smartphone. The home equipment is linked wirelessly via Wi-Fi technology to a household server, which can be controlled through the smart phone using an iOS application. In particular, the main objective of this work is to design a system named Wireless Sensor Actuator Mobile Computing in a Smart Home (WiSAMCinSM) that makes multifunctional contributions to assisting elderly people in their daily lives. Part of this system has been tested within the laboratory; firstly, through a WI-Fly Serial Adapter using Tera Term technology, and secondly, through WI-Fly and iPhone using the Ad hoc network. The prototype system consists of a Smartphone, Microcontroller Unite (STC89C52RC), WiFly-RN370 and seven sensors, as well as an iMac and a Personal Digital Assistant (PDA). The prototype system has been implemented based on the Smartphone and commercially available low cost sensors, actuators and logic converters. Results show great potential in employing the information and evaluation of high quality prototypes for the functions of data acquisition.
