Overview

CR206X Datalogger w/900MHz Spread Spectrum Radio (-40 to +50C)

The CR206X is a small, low-cost data logger that includes an internal 900 MHz spread-spectrum radio for transmitting data to another CR206(X), an RF401(A) radio, or an RF430 radio. The 900 MHz frequency is used in the US and Canada.

The CR206X provides stand-alone operation in harsh, remote environments. It reads input from one or two sensors, then transmits its data wirelessly via its internal radio. Multiple CR206Xs can be configured as a network, or units can be deployed individually.

Key Advantages

Smallest, Lowest-Cost Data Logger
Built-in spread-spectrum radio

Technical Description

The CR206X can be used in a wireless sensor network. Wireless sensor networks are appealing because they are often more economical than trenching, laying conduit, and pulling wire. When used as a wireless sensor, the CR206X measures the sensors attached to it, then transmits its data wirelessly via its spread-spectrum radio to a master data logger. The master data logger must support the PakBus communication protocol (e.g., CR800, CR850, CR1000, CR3000). For more information on how to configure a PakBus system, please read our PakBus Networking Guide.

The CR206X has several input channels for measuring a variety of sensors. Gas discharge tubes provide rugged electrostatic discharge protection for the inputs.

The CR206X does not make differential measurements and is not compatible with SDM devices, multiplexers, or thermocouples (refer to the Compatibility information for compatible sensors, peripherals, and software). Recalibration services are not offered for the CR206X datalogger.

Benefits

  • Small, low-cost data logger with internal spread spectrum radio for wireless communications
  • Integrated radio lets this data logger function like a wireless sensor in a network, transmitting to a master data logger
  • Ideal applications include wind energy, rural water, water level/flow, aquaculture, water quality
  • Gas Discharge Tube (GDT) protected inputs
  • Optimal for measuring one or two simple sensors
  • Makes SDI-12, single-ended analog, pulse, switch closure, and bridge measurements
  • Battery-backed clock that ensures accurate time is maintained while data logger is disconnected from battery power
  • Program with LoggerNet, PC400, or Short Cut to fit your setup
  • PakBus, Modbus, and SDI-12 protocols supported
