The Stevens Data Online Telemetry (DOT) Logger is a flexible, compact, and inexpensive data logger specifically designed for accurate measurements from a variety of sensors. The DOT Logger’s design includes four analog and four pulse count inputs, and can monitor up to 190 channels from multiple SDI-12 sensors in remote environmental applications.
The DOT Logger telecommunications options include satellite transmitters (geostationary such as GOES or low earth orbiting such as ORBCOMM), cellular or PTSN modem, or radio (UHF, VHF, spread spectrum). Free software that is shipped with the DOT Logger includes DOT SET for easy set up and configuration of the DOT Logger and Stevens LoggerXL (part of AxRead) for simple exchange of data between the DOT Logger and a computer. Once downloaded to a PC, the data can easily be viewed in a comparable tabular or graphical format or exported to MS Excel or other programs.
This flexible data collection package with the telemetry options easily brings the remote site monitoring information to your computer and/or standard web browser software.
