| 摘 要： | 采用Intersema公司基于MEMS的数字压力传感器MS5534C,利用海拔高度与气压和温度的关系,设计并制作了一个数字气压计。利用单片机P89LPC936的I/O口控制,实现了P89LPC936从数字压力测量模块MS5534C读取气压数据,并通过软件计算处理转换为当前海拔高度的功能,且在LED显示屏上实时显示海拔高度。设计的数字气压计样机具有质量小、功耗低、精度高等优点,经过在多个地段进行试验,在标准大气压环境中其相对高度测量的平均标准偏差为3 m。

| Abstract: | According to the relationship among pressure, temperature and altitude, a digital barometer with MS5534C digital pressure sensor based on MEMS of Intersema company was designed. Use I/O control of single chip P89LPC936 to realize P89LPC936 to receive air pressure data from digital pressure measuring module MS5534C, transfer data to current altimeter by software processing, and display altimeter on LED displayer in real time. The barometer prototype has advantages of light weight, low power cost, high precision. The barometer was tested in the standard atmospheric condition, which has a relative altitude average standard deviation of 3 m. |
