氣壓是氣象監(jiān)測(cè)中的一個(gè)重要參數(shù)，提出了一種氣壓數(shù)據(jù)采集模塊設(shè)計(jì)方案，該模塊采用數(shù)字氣壓傳感器MS5534B、MSP430單片機(jī)MSP430F2272和帶實(shí)時(shí)時(shí)鐘（RTC）64 KB鐵電存儲(chǔ)器。通過(guò)低功耗軟件設(shè)計(jì)方法以微安級(jí)整體平均功耗實(shí)現(xiàn)了氣壓數(shù)據(jù)的采集和存儲(chǔ)，適合電池供電的連續(xù)高精度氣壓采集應(yīng)用。給出了模塊的軟硬件設(shè)計(jì)以及MS5534B的性能指標(biāo)和使用經(jīng)驗(yàn)。
Abstract:
Air pressure is an important parameter in weather monitor.This paper futs forward a new design scheme of low power-air pressure data acquisition module.The module uses a digital output barometer sensor MS5534B,MSP430 microcontroller MSP430F2272 and integrated RTC 64KB FRAM,precision air pressure measurement and storage chip.Another point of this module is low power consumption, so it is well suited for battery powered air pressure data acquisition applications. At the same time,the software and hardware deign of module is presented,And the speciaties and use notices of MS5534B are given.
