Appendix F. Other Campbell Scientific Products 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 132. 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 Table 133. Sensors Types Available for Connection to CWS900 Air temperature Relative humidity Dissolved oxygen Soil heat flux Infrared surface temperature Soil temperature Leaf wetness Solar radiation Pressure Surface temperature Quantum sensor Wind speed / wind direction Rain 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 CR3000. Excitation channels can also be multiplexed. Table 134. Analog Multiplexers Model Description AM16/32B 64 channels - configurable for many sensor types. Muliplex analog inputs and excitation. AM25T 25 channels - designed for thermocouples and differential inputs 562
