CONTROLLING OF RELAY USING RASPBERRY Pi VIA INTERNET FOR HOME AUTOMATION

The Relay Module is a device that switches power to auxiliary devices. 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.
