SHT11数字式温湿度传感器在温湿度监测中的应用

SHT11 is a digital Temperature and Humidity Sensor which has the features of high measurement precision, fast response time, simple interface and so on. In this paper,the working principle of SHIT11 is introduced, the MCU interface circuit,the assembler of instructions sequence,and the measuring process are explained.With SHT11 as a sensor,the monitoring uint of temperature and humidity is designed , which is successfully adopted in a flash network monitoring system.
