基于AT89S51单片机的温湿度监测与控制系统设计与应用研究

Design and Application of Temperature and Humidity Monitoring and Control System Based on AT89S51 Microcontroller

温湿度控制在人们的生产生活中具有重要意义。通过温度计、湿度计对温湿度进行数据采集,再经过人工加热、人工加湿、通风和降温等设备调节温湿度。但是,这种控制方法很难保证控制效果的准确性,操作费神费力。一些行业对温湿度的要求较高,温湿度较高或者较低均可能导致元器件失效,也可能导致事故的发生,不利于系统正常运行。因此,研究基于AT89S51单片机的温湿度监测和控制系统设计方案,提出了一种性能好、成本低的温湿度控制系统设计方案。

Temperature and humidity control is of great significance in the application of people’s production and life. Through thermometer, hygrometer for temperature and humidity data collection, and then through artificial heating, humidification and ventilation and cooling equipment to adjust the corresponding temperature and humidity, but this control method is difficult to ensure the accuracy of the control effect, the operation is also laborious. However, some industries have high requirements for temperature and humidity. High or low temperature and humidity may lead to component failure or accidents, which is detrimental to system operation. In this regard, this paper studies the temperature and humidity monitoring and control system design scheme based on AT89S51 microcontroller, and explores a temperature and humidity control system design scheme with good performance and low cost.
