介绍了一种基于AVR单片机的简易智能家居监控系统,包括系统整体结构、硬件电路及软件设计。系统采用Atmega16处理器,通过温度传感器SHT11收集温湿度信号,利用液晶显示器SO12864-14C显示当前的温度、湿度及结露点;通过红外传感器LHI778,实现防盗检测功能,当人体进入红外感应范围,系统发出信号报警。
This paper introduces a simple intelligent home monitoring system based on AVR microcontroller, including the overall system structure, hardware circuit and software design. The system uses Atmega16 processor, through the temperature sensor SHT11 to collect temperature and humidity signals, the use of liquid crystal display SO12864-14C display the current temperature, humidity and dew point; through the infrared sensor LHI778, anti-theft detection function, when the human body into the infrared sensing range, the system issues Signal alarm.
