After a review of the recent advancements in wireless automation systems, the paper introduces an efficient and economical automation system based on GSM technology. The proposed system uses Atmel AT89S52 as a central microcontroller which is cheaper, faster and can perform same functions as PIC microcontroller. The system will allow remote control of different appliances through SMS messages. In addition, in case of any faults or warnings detected by the system, an SMS message will be send directly to the owner of the system. The owner of the system can request status reports from the system at any time.
