Overview

The CWB100A is the master radio in a Campbell Scientific wireless-sensor network. It polls and stores data from up to 50 wireless sensors, and then passes that data to a data logger. Its internal radio has a 920 to 928 MHz frequency range, which is used in Australia, Israel, and other countries worldwide.

Detailed Description

The CWB100A is the base station used in a Campbell Scientific wireless sensor network. It contains an internal 922-MHz spread spectrum radio that receives data from the wireless sensors in the network. The frequency of the CWB100A's internal radio is commonly used in Australia and New Zealand. The data logger is connected to the CWB100A for processing and storing the wireless sensor's data.

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.

Additional Compatibility Information

数据记录器被编程为与CWB100A接口并确定轮询间隔。传感器在轮询时进行测量。基站轮询所有传感器并早期存储收集的数据,以便在数据记录器请求它时,它可以立即传输数据。这最小化了数据记录器需要等待通过CWB100A基站从网络响应的时间量。

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.
