基于气压传感器BMP085的高度测量系统实现
Implementation of height measurement system based on pressure sensor BMP085
摘要
Abstract
This paper designs a kind of height measurement system based on BMP085 pressure sensor . With STM32F103RCT6 embedded chip as the main controller for the system , use the way of I 2C hardware interface to read the pressure data that the BMP085 measures , and do compensation to the pressure data with the temperature data . Then adopt linear interpolation method to calculate the absolute height based on the relationship of atmospheric pressure and altitude . Thereby acquire the relative height . The experimental result shows that the relative height measurement error of this system is 0 . 4 m , thus can achieve high precision re-quirement .关键词
