基于单片机的智能温湿度控制系统设计

Design of Intelligent Control System of Temperature and Humidity Based on Single-chip Microcomputer

基于单片机的温湿度感测系统,以单片机为核心,由温湿度传感器SHT11、1602液晶显示等模块组成。通过SHT11对环境的温度和相对湿度进行检测,通过二线串行接口将数字温湿度信号送至单片机,由单片机完成相对湿度的非线性补偿,并将实际温度和相对湿度值送液晶显示器显示,从而实现对环境温湿度的测控。

Temperature and humidity sensing system based on single-chip microcomputer, taking single-chip microcomputers as a core, is composed of different modules including SHT11 temperature and humidity sensor, 1602 character LCD. It tests the temperature and relative humidity of the environment by SHT11, and sends the digital signal of temperature and relative humidity to single-chip microcomputer through two-line serial interface. At last, the single-chip microcomputer realizes the nonlinear compensation of the relative humidity, and displays the real temperature and relative humidity values on LCD. Accordingly, the measure and control of the environ- mental temperature and humidity are realized.
