The control system for smart home based on GSM and the radio

In order to guarantee the effective control to the appliances and ensure the safety of living environment, a control system for smart home has been designed. Based on the GSM network service and wireless communication, the system is developed with the MCU AVR mega 16 as the core. It can be divided into two working patterns: the long-distance pattern and the short- range pattern. Experiments have proved the two outstanding functions: under the long-distance pattern, the user can obtain long-distance monitoring of the living environment and get remote control to appliances through the GSM network service; under the short- range pattern, the user can observe the room environment condition through LCD and realize the short- range control to appliances using radio.
