摘　　要：针对当前气压传感器功耗偏大、输出数据单一、灵活性差等缺点,设计了一款低功耗、输出方式灵活的智能型气压传感器。以ATmega16L单片机为主控芯片,通过SPI总线读取气压和温度的原始测量值,计算得到精确大气压值;采用精细化的软硬件省电设计方法,实现了系统的低功耗;通过跳线选择数据输出方式,增加了产品的灵活性。该传感器具有高精度、高稳定性、智能性、低功耗和便携式等特点,可独立使用,也可用于其他需要气压测量的设备中。At present, the air pressure sensors features demerits of larger power consumption, unitary output data, and poor flexibility, etc. , thus the intelligent air pressure sensor featuring low power consumption and flexible output modes has been designed. With ATmegaI6L single chip computer as the main control chip, the raw measurements of temperature and air pressure are read through SPI bus; then accurate value of barometric pressure is calculated. The low power consumption is implemented by meticulous hardware and software power-saving design; the flexibility of products is reached through selecting output mode by jumpers. The sensor features high accuracy, high stability, intelligence, low power consumption and easy to carry,it can be used standalone or used in other measuring devices need to measure air pressure.
