针对传统有线数据采集技术存在的可移动性差，电线铺设受环境影响大等问题，运用短距离无线通信技术，采用挪威 Nordic 公司的单片射频发射器nRF905设计出了一个自动气象站系统，采集湿度、压强、温度、光照等气象站数据。通过nRF905芯片，将采集而来的数据经无线通信信道传输至接收端并用LCD12864液晶显示器显示出来。nRF905芯片工作电压为1.9~3.6 V，工作于433 MHz/868 MHz/915 MHz 三个ISM频道（全球免费波段），芯片功耗非常低。此系统可广泛应用于无线数据采集、环境监测等场合，有很好的灵活性和良好的实时性。

In allusion to the problem of poor mobility and large environment effect of cable laying existing in traditional data acquisition technology via the wire,an automatic weather station system with single chip RF transmitter nRF905 of Nordic Com-pany is designed,which using short distance communication technology,to collect the meteorological data of humidity,tempera-ture,illumination and so on. By using nRF905,the collected data is transmitted to the receiving end through wireless communi-cation channel,and displayed by LCD12864. nRF905 has low power consumption,and works in 433 MHz/868 MHz/915 MHz three ISM channel(Global free band),whose working voltage is in the range of 1.9~3.6 V. The system can be widely worked in the field of wireless data acquisition and environment monitoring,and is flexible and real-time.
