Intelligent indoor wireless laser alarm system based on STM32
This thesis has designed an intelligentindoor wireless laser alarm system which takes Microcont roller Unit STM32F103 as the core.The system consist s of Micro controller Unit,GSM w ireless transceiver,matrix keyboard,sound and l ightalarm and pyroelectric laser sensors.Pyroelect ric laser sensor receives infrared signal which would be analysed by STM32F103.Alarm signal would be send out by the sound and lightalarm module.In the meantime GSM would transmit short message to the mobile of user through mobile network to reflect the circumstances of the alarm location.Because of the wide mobile network,the syst em is unnecessary to set up special network and maintain it.Therefore,it has unique advantages compared with the traditional monitor systems.
