Overview

The CR300 is a multi-purpose, compact measurement and control data logger. This small, low-cost, high-value data logger offers fast communications, low power requirements, built-in USB, and excellent analog input accuracy and resolution. The CR300 can measure most hydrological, meteorological, environmental, and industrial sensors. It concentrates data, makes it available over varied networks, and delivers it using your preferred protocol. It also performs automated on-site or remote decision making for control and M2M communications. The CR300 is ideal for small applications requiring long-term, remote monitoring and control.

The CR300 includes Wi-Fi, cellular, or the following radio options for different regions:

  • CR300-RF407: US and Canada
  • CR300-RF412: Australia and New Zealand
  • CR300-RF422: Europe
  • CR300-RF427: Brazil

Note: Campbell Scientific does not recommend the CR300 for use as a PakBus router in networks with more than 50 devices. Large arrays or string variables may also reach memory limits. For such applications, a CR1000X Measurement and Control Datalogger is recommended.

Detailed Description

The CR300 is a low-powered data logger designed to measure sensors, analyze data, and store data and programs. A battery-backed clock assures accurate timekeeping. The on-board, BASIC-like programming language—common to all Campbell Scientific data loggers—supports data processing and analysis routines.

The CR300 wiring panel includes a switchable 12 V terminal, and analog grounds dispersed among six analog terminals.

Additional Compatibility Information

Sensors

With several channel types, the CR300 is compatible with nearly every available sensor. This includes analog output voltage (0 to 2.5 V) and current (0 to 20 mA or 4 to 20 mA) sensors, thermistors, and RTDs to name a few. It is also compatible with pulse or frequency output sensors such as anemometers, rain gauges, and flow meters. CR300 dataloggers are not capable of applying reverse excitation, and they cannot be used with some conductivity or soil matric potential sensors.

SDI-12, Modbus, and other serial sensors are supported with the RS-232 port and C1 and C2 as a Tx/Rx pair. The CR300 does not directly support RS-485 sensors.

Measurement & Control Peripherals

The CR300 is compatible with low current and voltage solid-state relays but not with SDM or CDM devices.

Software

The CR300 series is compatible with CRBasic (version 3.6 or higher).

Enclosures

An ENC10/12 or ENC12/14 enclosure is adequate for most CR300-based systems.

Communications

The CR300 can communicate with a PC directly via its USB port. Compatible telemetry devices include our RS-485 converters, digital cellular gateways, RF telemetry, and satellite transmitters (HDR GOES, Argos, Meteosat, Iridium, and Inmarsat). Data can be viewed on an iOS or Android device (requires our free LoggerLink app), CD295 DataView II Display, or other third-party devices.

Power

The CR300 uses an external power source and has a built-in charger/regulator. Intelligent power sourcing autoselects the highest voltage from three input sources (CHG, BAT, or USB) to operate in one of the following four modes:

  • UPS (recommended) - A 16 to 32 Vdc source, solar panel (SP10, SP20), or power converter (29796) is used to charge a 12 Vdc battery, such as our BP7 or BP12.
  • 12 Vdc battery or other reliable 12 Vdc source
  • Charge only - DC power supply (16 to 32 Vdc)
  • USB - Powered over 5 Vdc USB port for setup, programming, and testing (will not charge battery or boost USB power to provide 12 Vdc to the switched battery terminal SW12)

Downloads

CR300 Series OS v.11.01 (4.96MB) 23-07-2024

This download is for the CR300 series of dataloggers including all CR300 and CR310 models. Execution of this download places the Operating System file(.obj) on your computer. It also updates the CRBasic Editor compiler and support files. 

Why Update? This OS resolves several bugs found in the previous OS. See the revision history for a complete list. With this OS update, it is recommended that you also update the Device Configuration Utility to the most recent version so that new datalogger features are available in the utility.  

Note/Warning: Campbell Scientific always recommends updating operating systems on site if possible. When remote updates are required, it is recommended that you implement the necessary precautions to handle unexpected OS upload complications. All datalogger settings should be retained when updated remotely. If you choose to roll back to a previous operating system, the datalogger settings will be reset to default.
