Aiming at frequent events of fire and theft occurred in college dormitory, a remote monitoring system combining fire alarm with anti-theft is designed. The system uses LM3S811 as the core microprocessor, GSM as the remote wireless transmission module, MQ-2 smoke sensor and DS18B20 temperature sensor as the fire sensors, the pyroelectric infrared sensor as the anti-theft monitoring sensor, uses the infrared remote control way to change the parameter setting of the system. Through the signal processing algorithm the environment in dormitory is judged. The results of hardware system testing show that the system can quickly perceive the emergent situation in dormitories, and achieves the desired effects.
