一种基于单片机的风压温湿度检测仪的设计

A Design of Air Temperature and Humidity Detector Based on Microcontroller

针对风压温湿度检测仪功能单一和更换电池频繁的缺陷,文中介绍了一种基于NEC单片机的风压温湿度检测仪。该设计由SENSIRION公司生产的SHT15温湿度传感器、Microbridge公司生产的MB-LPS2-03系列风压传感器和日本NEC公司生产的78F0513DA单片机为核心组成。此多功能手持检测仪可以同时测量温度、湿度、风压等参数,配合皮托管使用,可测量气体流速和风量,显示界面上温湿度和风压同屏显示。该检测仪采用锂电池供电,续航能力强,使用方便。

Against the shortcomings of rare function and frequent replacing the battery of the air temperature and hu- midity detector, this paper introduces a kind of detector based on NEC microcontroller. This design is composed of the SHT15 temperature and humidity sensor from SENSIRION Company, the MB-LPS2-03 series air sensor from Microbridge Company and the 78F0513DA microcontroller from Japan NEC Company as the core component. This multi-function hand-held detector can measure temperature, humidity and the air pressure at the same time. It also can measure gas flow rate and air flow with pitot tube. Temperature, humidity and air pressure can display in one interface. The detector uses the lithium battery. Battery life is stronger. It is convenient to use.
