摘　　要：本文设计了一种基于HTU21D传感器的温湿度仪,介绍了HTU21D的驱动电路和单片机总线驱动程序。与传统温湿度测量装置的设计相比,本设计采用小型化传感器,并在热传递上做了优化,最大限度降低了其他电子元件对HTU21D的影响,并分析了其他影响HTU21D测量精度的因素,给出了相应的解决方案。A temperature and humidity meter based on HTU21 D sensor was designed. The drive circuit of HTU21 D and the bus driver of SCM were introduced. Compared with the traditional temperature and humidity measurement device design, this design uses a miniaturized sensor and optimized the heat transfer to minimize the impact of other electronic components on the HTU21 D. The article analyzes other factors that affect the accuracy of HTU21 D measurement and presents the corresponding solution.
