摘　　要：BMP085模块是一款高精度、超低能耗的大气压力传感模块。基于该芯片设计了一款新型智能输出的气压传感器。该传感器采用混合信号系统级芯片C8051F021作为数据采集处理器,进行新型海洋气象观测气压传感器的研制。文中对系统的硬件组成、软件设计进行了详细描述。对该气压传感器的样机标定试验表明,经校准后误差在0.3 h Pa以内,已经达到国外同类传感器水平。该传感器具有性价比高、精度高、稳定性好、功耗低、安装使用简便等优点,可广泛应用于气象站、船舶气象仪器、大型海洋资料浮标等场所。The BMP085 module of Germany BOCH company is a high-precision,ultra-low-energy atmospheric pressure sensor module. We designed a new type of intelligent output pressure sensor based on this chip. The sensor used the mixed-signal system level chip-C8051F021 as the data processor. For the development of this new marine meteorological barometric pressure sensor,system hardware components and software design method were described in detail. Calibration test of the pressure sensor prototype shows that the error of the sensor is less than 0. 3h Pa,which has reached similar foreign sensors level. The sensor has low cost,high precision,good stability,low power consumption,easy installation and use,and other advantages,which can be widely applied to weather stations,marine meteorological instruments,large ocean data buoys and other places.
