Campbell Scientific CWS900 wireless sensor interface

Click2Contact

The CWS900 wireless sensor interface allows a variety of sensors to be used in a wireless sensor network. It can be used for making measurements in locations where the use of cabled sensors is inappropriate, including 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.

The wireless sensor contains an internal 900 MHz spread spectrum radio that transmits data to the Campbell Scientific CWB100 wireless base station or to another wireless sensor. The frequency of the device’s internal radio is commonly used in the US and Canada.

A wireless sensor can route its transmissions through up to three other wireless sensors. A data logger is connected to the CWB100 base station for processing and storing the CWS900’s data.
