概要
The CWB100E is the master radio in a Campbell Scientific wireless-sensor network. It can poll and store data from up to 50 sensors, and then pass that data to a data logger. The timing of polling and the number of sensors is configurable. The CWB100E uses a frequency-hopping, spread-spectrum radio for long range and less interference. The 868 MHz frequency is used in Europe and other areas worldwide.

詳細
The CWB100E is the base station used in a Campbell Scientific wireless sensor network. It contains an internal 868-MHz spread spectrum radio that receives data from the wireless sensors in the network. The frequency of the CWB100E's internal radio is commonly used Europe. The data logger is connected to the CWB100E 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.

Data Logger Considerations
The data logger is programmed to interface with the CWB100E 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 CWB100E 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.
