The Design of Temperature and Humidity Measure Based on USB Interface

摘要

To expand the using occasions, a kind of temperature and humidity measurement based on USB interface has been completed in which SHT10 is used as the temperature and humidity data collecting sensor, and the relative humidity is compensated by temperature at the same time. The USB interface chip CH340T is used to transfer the received data to PC for processing. In this paper, the system is described in detail from two aspects, hardware and software. Experiment shows the system has good measurement results.
