技术说明
CWB100A基站用于Campbell Scientific的无线传感器网络，它含有一个内部的922-MHz射频电台，可从网络内的无线传感器收集数据。CWB100A的无线频段通常用于澳大利亚和新西兰。数据采集器连接到CWB100A，来处理和存储无线传感器的数据。
为什么选择无线传感器？
在那些使用有线传感器会产生一些问题的站点，继续使用有线方式会有一些问题。首先，为了保护线缆，需要穿管、挖沟，既费时又费力，有些时候甚至没有可能性。当地的防火规范可能会禁止建筑内部使用某些类型的线缆。在某些应用中，测量需要通过较长距离实现，而较长的线缆可能会降低测量质量，或者成本太高。还有些时候，增加测量的数目非常重要，而数据采集器又没有留有足够的通道用于接入额外的传感器线缆。

Additional Compatibility Information
The data logger is programmed to interface with the CWB100A and determine a polling interval. The sensors make their measurements as they are polled. The base station polls all sensors and stores the collected data early enough that it can transfer the data as soon as the data logger requests it. This minimizes the amount of time the data logger needs to wait for a response from the network through the CWB100A base station.
At the start of each polling interval, the data logger polls the base station, and sensor values are transferred to the data logger for storage. This method of data transfer from the sensors to the data logger provides the fastest and lowest power method available.
