| 摘 要： | 采用Intersema公司基于MEMS的数字压力传感器MS5534B,利用海拔高度与气压和温度的关系,设计并制作了一个微型气压高度计。利用MSP430F449的I/O口模拟同步串行外设接口(SPI),实现了MSP430F449从数字压力测量模块MS5534B读取温度和气压数据的功能,经过相关的计算处理得到实际高度值,在液晶显示屏上实时显示温度和高度,并通过RS232通信接口把数据发回至上位机。设计的气压高度计样机具有质量小、功耗低、精度高等优点,经过实验测定,在标准大气压环境中其相对高度测量的平均标准偏差为0.2m,线性度为0.9999。

| Abstract: | According to the relationship among pressure,temperature and altitude,an altimeter system with MS5534B based on MEMS was designed.MS5534B is a digital pressure sensor produced by Intersema.The function of SPI was simulated using the I/O in MSP430F449,which can make MSP430F449 to receive data from MS5534B.Thereafter it can transfer the data which have been processed to the LCD,also it can return the data to the control computer through RS232.The light weight,low power,high precision altimeter was tested in t... |
