集成一体化干湿球温湿度传感器的研究

摘要

The development of the temperature humidity sensor has a long history, and many new models are invented at the same time. This paper bases on the theory of dry-wet bulb, designs the hardware circuit of the dry-wet bulb temperature and humidity sensor data acquisition system. In order to ensure that temperature and humidity measurement precision, the hardware circuit error analysis, put forward the system error of the method to improve.%温湿度传感器发展的历史很悠久，同时也出现了很多新型温湿度传感器。本文重点在干湿球理论的基础上，设计了干湿球温湿度传感器的数据采集系统硬件电路。为了保证温湿度测量精度，对硬件电路进行了误差分析，并且提出了系统误差的改善方法。
