According to the measurement ocassion of Ground Stations multi-point observations and meteorological observation aircraft airborne towed,a temperature and humidity acquisition circuit based on platinum resistance and HIH-5030 is proposed. In this system,Embedded software which has real-time waveform display software based on Qt/E can firstly be taken to collect multiple data by FPGA, and then, SQLite3 datebase is used to storage temperature and humidity data. Humidity error of this new system is less than 1% and temperature error is less than 0. 2 ℃ compared with optical chilled mirror dew point sensor. Moreover,this sensor circuit can get fast response speed,as well as accurate and stable real-time waveform interface, so that it can be used in the measurement ocassion of Ground Stations multi-point observations and airborne towed.
