摘　　要：SHT11是瑞士Sensirion公司生产的具有I2C总线接口的单片全校准数字式相对湿度和温度传感器。该传感器采用独特的CMOSensTM技术,具有数字式输出、免调试、免标定、免外围电路及全互换的特点,但对无I2C总线接口的单片机却无法与之直接相连。可借助通用I/O口线来虚拟I2C总线,即采用虚拟I2C总线协议的编程方法实现与之接口。SHT11 is a single chip digital Relative humidity ＆ temperature sensor with I^2C Bus made by Sensirion Co. in Switzerland. The sensor uses CMOSens technology and is of the most advanced functions, however there is a shortcoming for it. The problem can be solved with a programming method of Simulation I^2C bus .
