Paper Abstract

An intelligent measure instrument of temperature and humidity was developed, which has the following functions: real-time examining, saving and showing the temperature, the humidity and the dew-point of environment, displaying dynamically date and time, and saving all data records when the power is off. It can not only dynamically draw the temperature-time curve and the humidity-time curve, but also perform the statistical analysis on the data saved by the instrument and produce a report in the Excel format. The system can calculate the maximum, the minimum, the average and the variance of the data records. The instrument communicates with the PC through the USB interface, which can be conveniently used to measure temperature and humidity in a variety of environments.
