详细说明
CWS900具有密封的连接器，用于连接一个雨量，风传感器，温度/RH探头或其他低功率传感器。它测量模拟电压，低水平的交流电，脉冲计数，并可以提供激发电压，以供电某些传感器或进行桥梁测量。传感器执行的测量类型是使用无线传感器计划器，网络计划器或DevConfig软件配置的。CWS900与PC接口通过A205 CWS传感器到PC接口进行配置。
CWS900可以通过最多三个无线传感器路由其传输。数据记录器连接到CWB100基站，用于处理和存储CWS900的数据。
CWS900是使用碱性电池或可充电电池和太阳能电池电池供电的电池。
Why Wireless?
There are situations when it is desirable to make measurements in locations where the use of cabled sensors is problematic. Protecting cables by running them through conduit or burying them in trenches is time consuming, labor intensive, and sometimes not possible. Local fire codes may preclude the use of certain types of sensor cabling inside of buildings. In some applications measurements need to be made at distances where long cables decrease the quality of the measurement or are too expensive. There are also times when it is important to increase the number of measurements being made but the data logger does not have enough available channels left for attaching additional sensor cables.
不te:The internal radio is not designed to move a lot of data quickly. It takes 15 to 30 seconds per hop when moving data from a sensor, through a sensor used as a repeater, and ending up at the base radio. Going through three repeaters could take a data packet anywhere from 45 to 90 seconds to get to the base radio.
