Use relay modules to control switched devices and appliances like lighting, heating, air conditioning, pumps, motors, dampers, elevators, door locks, door releases, and grounds irrigation equipment, all from computer system keypads by interfacing raspberry pi model B. By integrating relay outputs into an intrusion, fire alarm, panic, or access control system, the system creates a nervous system for the building, allowing facility systems to sense status of doors, windows, and occupancy to distribute services to rooms or departments as needed. This is essential for cost control for facilities small and large. Here in this paper, relay has been controlled through Raspberry Pi Model B, in order to control home appliances for home automation. By using a home automation system, we can save a lot of time to operate home appliances from anywhere without wasting time to move from office to home for just unlocking door for family members to enter the home. Key words: Raspberry Pi, Relay, Putty software, Internet, Home automation.

INTRODUCTION Today we are living in 21 st century. It is necessary to control the home from desire location. Home automation is the control of any electrically and electronics device in our home and office, whether we are there or away. There are hundreds of products available that allow us to control over the devices automatically with using raspberry pi model either by remote control or even by webpage. Home automation refers to the application of computer and information technology for control of home appliances easily and reducing the power consumption or the power wastage associated with the manual system. Its application varies
