基于AT89C51控制的幼儿园睡眠区温湿度监控系统的设计

A Design of Temperature and Humidity Monitoring System in Kindergarten Sleeping Area Based on AT89C51

摘要: 介绍了一款利用AT89C51单片机作为核心控制设备，DHT11型的温湿度传感器为主要测量设备的温湿度控制系统。利用本系统来控制幼儿园睡眠区的温湿度。将温湿度传感器的测量值送到单片机进行内部处理，结果通过LMG7135PNFL显示出来。幼儿园里温湿度的上下限通过键盘进行人工预设，当温湿度超过设定值时，报警电路里的灯光报警器就报警，同时温湿度的控制电路也要同步运行起来，从而保证幼儿睡眠区一直处于幼儿生长最佳环境的状态下，仿真结果显示系统有效可行。

Abstract: This paper introduces a temperature and humidity control system using AT89C51 microcontroller as the core control device and DHT11 temperature and humidity sensor as the main measuring device. Use this system to control the temperature and humidity in the sleeping area of kindergarten. The measurement value of temperature and humidity sensor is sent to the microcontrollers for internal processing, and the result is displayed by LMG7135PNFL. Kindergarten through artificial default keyboard, temperature and humidity of the upper and lower limits when temperature and humidity more than the set value, alarm lights alarm circuit was alarm, at the same time, the control circuit of temperature and humidity to synchronize to run, so as to ensure the sleeping area has been in kindergarten grows best environment conditions, the simulation results show that the system is effective and feasible.
