基于单片机的智能家居防火防盗

报警系统

摘要

随着社会的不断进步和科学技术、经济的发展，人们的生活水平得到很大的提高，人们愈加注重人身安全,因而也对防火防盗措施提出了新的要求。

本设计所做的智能家居控制系统包括室内信息智能监控功能、输入与实时显示功能、声光报警功能等。本文利用单片机结合传感器技术而开发设计了这一防火防盗报警系统。本设计采用DYP-ME003人体红外感应模块、18B20温度传感器和MQ_2烟雾传感器检测信号,然后将信号传送给单片机智能手机解锁处理，实现声光报警.该系统通过按键对系统的温度和烟雾的浓度进行初始化设置，利用LED显示模块对系统的温度和烟雾的浓度进行实时显示.京能恒基该系统结构简单、性能稳定、使用方便、价格低廉，具有一定的实用价值。

Abstract

With society’s progress and development of science and technology， economy, people's living standard has been greatly improved. People pay more attention to personal safety, thus they put forward new requirements for the fire and security measures。

In this design ,the intelligent family- house control system includes this function : indoor information intelligent monitoring ， the input and real-time display ，sound and light alarm, and so on 。The design is a fire and security system, which combines sensor technology with microcontroller. This design adopts the DYP-ME003 human body infrared sensor module，18b20 temperature sensor and MQ_2 smoke sensor to detection signal. These sensor send the signals to microcontroller。The microcontroller process these signal and drive alarm circuit to achieve sound and light alarm 。The fir temperature and smoke concentration are initialized in this system.，and are displayed in the LED display 。The system has the advantages of simple structure ,stable performance ,conventional operation ,low price ，and has a certain practical value .
