| Abstract: | According to the relationship among pressure,Abstract:According to the relationship among pressure,temperature and altitude,a mobile barometric altimeter with altimeter sensors MS5607B is designed.The system is powered by a rechargeable lithium battery.STM32L152 as a ultra-low power processor is used to receive the pressure and temperature which sampled by MS5607B.Data filtering,temperature compensation and height calculation are carried out with the software.The worked data which have been processed to the LCD,also can be stored as a file in SD card via transplanting file system FatFS.Through the USB interface of the system,data files can be read or copied by PC by way of modifying the USB firmware library.The barometric altimeter designed in the paper is mainly features by small,portable,low power,high accuracy and data backup.The experiments show that the system works stably and makes a fine performance. |
