Overview
The CR300 is a multi-purpose, compact measurement and control datalogger. This small, low-cost, high-value datalogger 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 series 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
Benefits and Features
Connects directly to a computer's USB port
Differentiates even slight changes in data values with higher resolutions measurements (24 bit Adc)
Provides simple serial sensor integration and measurement with SDI-12 and/or RS-232
Supports full PakBus networking
Includes embedded web page for direct connection via web browser
Detailed Description
The CR300 is a low-powered datalogger 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 dataloggers—supports data processing and analysis routines.
The CR300 wiring panel includes a switchable 12 V terminal, and analog grounds dispersed among six analog terminals.
