Design of Wireless Home automation and security system using PIC Microcontroller

Abstract—The development of the new technologies in the field of electronics has brought tremendous changes in the day to day life of every human being. They have entered the fields like industry, medicine, telecommunication and also home automation. This paper introduces the intelligent home automation system (IHAM) which is developed using PIC microcontroller with the ZigBee wireless communication technology, speech recognition technique and GSM network technology that control the home appliance. The automation centres on recognition of voice commands and uses low-power RF ZigBee wireless communication modules which are relatively cheap. The home automation system is used to control all lights and electrical appliances in a home or office using voice commands with help of HM2007 chip that is widely used for such appliances. The proposed system gives the overall framework of hardware and software design, and describes ways to implement the system. The paper also explains the security system for fire hazards that may occur through smoke sensor and GSM Module that is controlled by the same controller that sends the SMS to the user if the smoke is detected.
