About Dataloggers & Data Acquisition Systems
Campbell Scientific dataloggers are at the center of our rugged, reliable data acquisition systems. Our dataloggers share similar measurement and programming capabilities; selection of the appropriate datalogger depends mainly on the type, number, precision, and speed of measurements required.

Datalogger Overview
Multiplexers and/or SDM devices may be added to augment measurement and control capabilities that include:
- measuring most sensors
- providing non-volatile data storage and on-board battery-backed clock (excludes CR7)
- on-board data processing
- initiating measurement and control functions based on time or event
- controlling external devices such as pumps, motors, alarms, freezers, valves, etc.
- using our PC support software or keyboard/display to program
- operating independently of ac power, computers, and human interaction
- consuming minimal power from a 12 Vdc source
- interfacing with on-site and telecommunication devices such as telephone modems (including cellular and voice-synthesized), short haul modems, radio transceivers, satellite transmitters, and ethernet interfaces
- operating temperature range of -25° to 50ºC; optional extended ranges are available

Dataloggers, which may also be referred to as Measurement and Control Units (Systems) or Microloggers, are the heart of a data acquisition system. They measure sensors at a specific scan rate, process data, store the data, and initiate telecommunications. Our dataloggers also have control capabilities allowing them to respond to specific site conditions by opening flood gates, turning fans off/on, etc.
The official definition of SDI-12 is Serial Data Interface at 1200 baud. Having stated that, SDI-12 is a protocol that was developed within the water resources field to make it easier to determine if a sensor and a datalogger were compatible. Instead of having to work through the specifications of the datalogger and the sensor for output, input, excitation, wiring, power, programming, etc., all SDI-12 sensors would have just three wires—a serial data line, a ground line, and a 12 Volt power line.
The CR510, CR500, CR10X, CR23X, CR800, CR850, CR3000, and CR1000 can be used for Modbus applications. The CR510, CR500, and CR10X require a special Operating System; Modbus protocol is standard in the CR23X, CR800, CR850, CR3000, and CR1000. If you already have a CR510, CR500, or CR10X and you want to use it for a Modbus application, you can purchase an operating system with the Modbus protocol and download it to the datalogger using CSOS downloading software or the DevConfig Utility.
