51单片机控制智能家居监控系统设计仿真
本设计：
仿真版本：proteus 8.9
程序编译器：keil 5功能介绍：
以提高家居生活的安全性、舒适度、人性化为目的，设计智能家居监控系统。
（1）设计必须实现家居温度、煤气泄漏、外人闯入、火灾（烟雾）的全部检测；
（2）各检测节点可通过无线方式连接到主机，检测到危险信号后，主机采用声光报警或远程报警；
（3）系统具有检测灵敏、报警及时、性价比高等特点；
（4）拓展部分：增加检测项目并具有可行性，除环境检测外也可增加人体信号（心率、体温）检测等。
分析：为实现温度检测、煤气和烟雾等气体检测、监控外人闯入等功能，采用NTC热敏电阻、MQ2气体检测传感器、磁控开关等传感器。资料下载链接（可点击）：
