摘要
通过温度传感器DS18B20,气体、烟雾传感器采集的家居信号经ATM ega128单片机处理,通过BENQ的GPRS模块M23发送监测信息到监控终端或者用户手机,从而达到监测的目的。人体热释电红外检测到有人闯入家居时,单片机则启动CMOS摄像头抓拍,把照片用GPRS方式发给用户或服务器,达到安防的目的。该系统比一般的嵌入式系统开发周期短,硬件成本低,且系统设计简单,性能可靠。
Household signal which collected through the DS18B20 tmperature sensor、gas、smoke sensors processed by ATmega128,then the purpose of monitoring is achieved by send monitering information to monitor terminal or users＇ mobile phone via the BENQ-M23 module.When someone broke into household,the infrared radiation emitted from human body will be received by the infrared human body detecting sensor,once enable CMOS camera,Finally,the photos will be sent with GPRS to a user or server so as to get security purposes.This systems has a shorter development cycle than embedded systems.What should be pionted out is that the costs of hardware is low and its design is simple with a reliable performance.
