The CR206 Datalogger features an on-board 900 MHz spread-spectrum radio with the functionality of the CR200 Datalogger. The CR206's input channel configuration and small size is optimal for measuring one or two sensors. When paired with an ENC200 enclosure and the small 16869 battery, the packaged CR206 has a deployment size of only 6 in. by 7 in. This small package is optimal for the CR206 to be used as a wireless sensor within a PakBus network. The CR206 measures the sensors attached to it, then transmits its data wirelessly via its spread-spectrum radio to a master data logger. For more information on how to configure a PakBus system, please read our PakBus Networking Guide in the Related Documents section. If an alternate spread-spectrum radio is required, see our CR211 and CR216 dataloggers.
