Temperature and Humidity Controller Based on SHT11

基于SHT11的数字温湿度控制器,以MSP430F149单片机为核心,由温湿度传感器、电源、液晶显示、键盘、声光报警及JTAG等模块组成。首先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MSP430F149微控制器,最后利用微控制器完成相对湿度的非线性补偿和温度补偿,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。

The digital temperature and humidity controller based on SHTI 1, which regards MSP430F149 single chip as the core, and is composed of temperature ＆ humidity sensor, power supply, LCD, keyboard, sound ＆ light alarm and JTAG module. SHT 11 firstly measures the environmental temperature and relative humidity. Then, the digital signal is transmitted to MSP430F149 controller. At last, the controller realizes the non-linearity and temperature compensation of the relative humidity, and transmits real temperature and relative humidity values to LCD. Accordingly, the measure and control of the environmental temperature and humidity are realized.
