The CR200 is our lowest-cost data logger. Its 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 CR200 has a deployment size of only 6 inches by 7 inches.

The CR200 is the base model in the CR200 datalogger series. Three related models, the CR206, CR211, and CR216, carry onboard, spread-spectrum radios, and the CR295 is specially equipped for use with the TX312 GOES transmitter.

Campbell Scientific’s SDM devices and multiplexers are not supported.


The CR200 cannot make differential measurements and is not compatible with thermocouples, our geographic position sensor, fuel moisture/temperature probe, and soil heat flux sensors. However, it can measure a variety of sensors including SDI-12 sensors and 4 to 20 mA sensors. Our CS625 Reflectometer, 109 Thermistor, and CS15 Electric Current Sensor were specifically developed for our CR200-series dataloggers. Other compatible sensors include wind sets, tipping buckets, and barometers. For a complete list of compatible sensors, see the CR200-series brochure.


The CR200 can communicate with a PC via direct connect, NL100 Ethernet interface, MD485 multidrop modem, and digital cellular modems. Data can be viewed on the CD295 DataView II display or a PDA (PConnect or PConnectCE software required).


Applications with minimal power requirements can use the ENC200 enclosure to house the data logger and the #16869 sealed rechargeable battery. The ENC200 cannot house a barometer or a battery that is larger than the #16869. However, an ENC10/12 or ENC12/14 enclosure is adequate for most CR200-based systems.

Power Supplies

When connected to the on-board charging circuit, the sealed rechargeable battery should be 7 Ahr or smaller. Using larger batteries with the data logger's built-in charger may result in excessive PC board heating. This is especially a concern when the battery is deeply discharged or failing with a shorted cell. Campbell Scientific also recommends that solar panels be 10 W or less and wall chargers be 1 A or smaller.

Frequently Asked Questions

Number of FAQs related to CR200: 3

Expand AllCollapse All

  1. The CR200X-series and the retired CR200-series dataloggers are NOT compatible with SDMs or multiplexers. If more channels are needed or may be needed in the future, consider purchasing a CR800, CR850, or CR1000 instead.

  2. The CR200-series datalogger is unique in that it does not have an on-board program compiler like other Campbell Scientific data loggers. This means that the CRBasic file (*.cr2) must be compiled on the computer first, and then the compiled binary file (*.bin) must be sent to the data logger. When a program is created in CRBasic, the last step is to compile the file and, therefore, create the program BIN file.

    It is very important that the compiler used to generate the BIN file match the operating system version in the data logger. If a BIN file is sent to the data logger and the compiled version does not match the current OS, the program send will fail and an "Incorrect OS Version" message will be displayed. 

    To help avoid issues with OS version mismatch, if the CR2 file is chosen as the file to download to the data logger, LoggerNet version 2.1b and greater will first query the data logger for its OS version and then attempt to find the matching compiler in the LoggerNet program files directory (by default, this is C:\Program Files\Campbellsci\LoggerNet). If the matching compiler exists, LoggerNet will compile the file and send that file to the data logger. Note that if the *.bin file is chosen, LoggerNet will not compile the file before sending it.

    The software CD that is shipped with each CR200-series datalogger contains the appropriate compiler for the data logger OS. Copy this file into the LoggerNet program files directory so that it is available for use by LoggerNet. In CRBasic, select this file as the compiler to be used when compiling CR2 files from the Options | Supported Loggers menu item.

  3. A practical maximum is to connect one multiplexer per every two control terminals on the data logger. Control terminals can be shared between multiplexers to increase the number of connected multiplexers. Sharing terminals, however, requires more complex wiring and programming. Users who would like to connect more than one multiplexer per every two control terminals are advised to contact a sales or support engineer at Campbell Scientific for assistance.
