Überblick
Das CWS900E ermöglicht es, verschiedene Sensoren in ein kabelloses Sensornetzwerk einzubinden (siehe 'Kompatibel mit').
Es enthält ein internes 868 MHz- Funkmodem, das die Daten zur CWB100 Basisstation oder zu einem anderen kabellosen Sensor überträgt. Die Frequenz des Funkmodems wird in Europa als Standard verwendet.

Technische Beschreibung
The CWS900E has a sealed connector for attaching one rain gage, wind sensor, temperature/RH probe, or another low power sensor. It measures analog voltages, low level AC, pulse counts, and can supply an excitation voltage for powering some sensors or making bridge measurements. The type of measurement that the sensor performs is configured using Wireless Sensor Planner, Network Planner, or DevConfig software. The CWS900E interfaces with the PC for configuration via the A205 CWS Sensor to PC Interface.
The CWS900E can route its transmissions through up to three other wireless sensors. A datalogger is connected to the CWB100E base station for processing and storing the CWS900E's data.
The CWS900E is battery powered using either alkaline batteries or a rechargeable battery and a solar cell.
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 datalogger does not have enough available channels left for attaching additional sensor cables.

Sensors
One sensor can be connected to the CWS900E. Sensors with the -CWS option will include a connector that mates with the CWS900E. Alternatively, a sensor can connect with the CWS900E via the A150 Desiccant Case.
A150 Desiccated Case
The A150 Desiccated Case has a -CWS cable termination option. It allows our CS450 and CS455 pressure transducers or other sensors that have a vented cable to be connected to the CWS900E. Sensors that measure analog voltages, frequency, and pulse can also use the A150 to connect with the CWS900E.
