The Research on Intelligent Humidity Measurement System

Abstract

In order to solve fast and accurate measurement of humidity problems, the measurement principle of the temperature and humidity sensor which based on the DHT95 is introduced in this paper. Explaining the DHT95's transmission interface characteristic, temperature and humidity data transmission principle, as well as hardware and software design method. Combining with high performance microcontroller C8051F920, intelligent humidity measurement system was been established. Result shows it has a simple structure, high precision, high measurement speed and low-power consumption.
