Control-A: Adruino -Controlled Appliances Via Wi-Fi And Sms

Today's various "intelligent" appliances are set to realize the concept of a smart home. Technological advancements have given rise to a personal area network in home environment, where all the automated appliances can be interconnected and monitored using a single microcontroller. This study aims to develop a system that is able to control lights and home appliances via Wi-Fi and SMS. The integrated, of wireless technologies in the system allows the user to remotely control and monitor lights and home appliances hence creating a space that is more comfortable, safer and a more independent life for the elderly and for the handicapped people. The interfacing of the system to home appliances is achieved by the use of Arduino Uno microcontroller and some peripheral devices. The ESP8266 Wi-Fi Shield that is based on the ESPI1 Wi-Fi module adds Wi-Fi functionality to the Arduino Uno. The microcontroller processes all of the incoming data and acts accordingly to switch the connected home appliances. The GSM Remote I/O Kit is a highly configurable SMS based board that adds SMS remote control functionality to the system. The GSM module is based on SIM800 which has a complete Quad-band GSM/GPRS feature to transmit Voice, SMS and data information with low power consumption. Overall, the system works properly with two modes working in paralel. A number of home appliances were switched ON and OFF with little to no time delay using Wi-Fi connoctivity. The SMS control suggests a way of controlling lights and home appliances from remote locations where Wi-Fi connectivity cannot handle the switching of output devices, The use of a router is recommended for stabilizing and extending the range of the Wi-Fi connectivity.
