Design of the Temperature and Humidity Intelligent Control System for Infant’s Room

设计一种基于AVR单片机的婴幼儿房温湿度智能控制系统,该系统以ATmega16L单片机为主控芯片,利用SHT10温湿度传感器对房间的温湿度进行数据采集,通过按键可分别调节温度、湿度的上下阈值以获得一年四季最适宜宝宝生活的室内温度和湿度范围,通过单片机对继电器控制,分别控制冷气机、暖气机、加湿器和抽风机的动作,从而完成室内温湿度的自动调节。另外,系统还具有定时自动通风换气功能,通风时间和时长也可由用户调整。该系统充分利用了ATmega16L单片机资源,简化了系统设计,具有硬件结构简单、成本低、工作稳定等优点。

This paper designs an intelligent control temperature and humidity system for the infant’s room based on AVR microcomputer.The system uses ATmega16L microcomputer as the main control chip.It uses SHT10 temperature and humidity sensor to collect data on the temperature and humidity of the room.The thresholds of the indoor temperature and humidity can be adjusted by the keys for the most suitable baby’s life throughout the year.The microcomputer can control the actions of air conditioners,heaters,humidifiers and exhaust fans,so as to complete the automatic adjustment of indoor temperature and humidity.In addition,the system also has a timing automatic ventilation function,the ventilation time and duration can also be adjusted by the user.This system makes full use of ATmega16L microcomputer resources,which simplifies the system design and has the advantages of simple hardware structure,low cost,stable work and etc.
