The houses of 21st century are about to become more human control and automated. The automation is upon us in a huge way and people are rapidly inventing new gadgets that enhance our lives. In the automation advancements, implementing the embedded systems for the purpose of home automation has led to an increase in the security and remote controlling of the appliances at home. The home automation system based on Field Programmable Gate Array (FPGA) Spartan is proposed to overcome the disadvantages of using Microprocessor and Microcontroller. FPGA is used as a core, instead of microcontroller, because of its flexibility, increase in better power efficiency and decreasing prices. This system is based on SMS technology and uses GSM network to establish the communication between mobile and controller. GSM system uses TDMA technique for communication purpose. Once the message is sent to GSM Module, it transmits the mobile voice and data services at the 850MHz, 900MHz, 1800MHz and 1900MHz frequency bands. FPGA Spartan receives input through I/O blocks and it transmits to GPIO Pins, which is connected to the load, lamp etc through driver circuit. This System is designed using VHDL in Xilinx 14.7 which is implemented in FPGA Spartan.
