CR215 Datalogger with 2.4 GHz Spread Spectrum Radio
Services Available
Repair No
Calibration No
Free Support No


The CR215 was a small, low-cost data logger with an internal 2.4 GHz spread spectrum radio. It was replaced by the CR216, has improved communication capability. The CR215 can be used within a CR216(X) network, but the CR216(X) needs to be in the transparent mode. Contact one of our application engineers for details.

Additional Compatibility Information


The CR215's internal spread spectrum radio can transmit data to other CR215 loggers or RF415 radios. It can also communicate with CR216(X) loggers, RF416 radios, or RF432 radios if they are set to the transparent mode. Certain CR215 settings must match the radio's settings for communications between the data logger and radio to be successful. The factory default settings of these devices might not match; therefore, they may need to be reconfigured before communications can take place. 

The CR215 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, Archer-PCon Field PC, or a user-supplied PDA (PConnect or PConnectCE software required).

Measurement & Control Peripherals

The CR215 is not compatible with SDM devices and multiplexers.


The CR215 can measure a variety of sensors including SDI-12 sensors and 4 to 20 mA sensors. It cannot make differential measurements and is not compatible with the freezing-rain/ice, fuel moisture/temperature, geographic position, present weather, soil heat flux, soil matric water potential, and strain sensors listed on our price lists.


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 CR215-based systems.

Power Supplies

The CR215 uses an external power supply and has a built-in regulator. 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 CR215: 2

  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. 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.
