F.1.2 Wireless Sensor Network
Wireless sensors use the Campbell wireless sensor (CWS) spread-spectrum radio
technology. The following wireless sensor devices are available.
Table 125. Wireless Sensor Modules
Model Description
CWB100 Series Radio-base module for datalogger.
CWS655 Series Near-surface volumetric soil water-content sensor
CWS900 Series Configurable, remote sensor-input module

F.2 Sensor Input Modules
Input peripherals expand sensor input capacity, condition sensor signals, or
distribute the measurement load away from the datalogger.
F.2.1 Analog Input Multiplexers
Analog multiplexers increase analog-input capacity beyond the channels integral
to the CR800. Excitation channels can also be multiplexed.
