Data files and format

Data that are read by the IoE Module will be uploaded to LI-COR Cloud™ automatically and routinely under normal circumstances. Data read while the device is offline (no network connection) will be stored locally and uploaded when the connection is restored, so long as an SD card is installed, the device has cellular service, and the IoE Module is registered with LI-COR Cloud.

The SD card stores files of measurement data and hidden files that are backup of the data uploaded to LI-COR Cloud. Here, we briefly describe the contents of the data files. The format is the same, whether the file is retrieved from the device SD card or downloaded from LI-COR Cloud.

Schedules

One CSV data file is created for each schedule that is running on the IoE Module. Under the default schedules, the IoE Module stores one record from the LI-710 every 30 minutes and one record from the HydraProbe every 10 minutes. If multiple sensors are on the same schedule, records from both sensors will be logged in a single CSV data file. Column headings indicate which data comes from which sensor.

Format

Data are stored as plain text files (.csv format) that can be opened in most spreadsheet applications and text editors. When downloaded from LI-COR Cloud, files are available as plain text (.csv) or Microsoft Excel (.xlsx). The frequency of records depends on the settings in the module, but typically a row of data is recorded every 30 minutes from the LI-710 and every 10 minutes from the Stevens HydraProbe, unless the setting has been changed on the IoE Module.

The header includes information about the file - including the devices that measured parameters, variable names, variable ID, units, and the data.

Data

Each record is presented with resolution and precision provided by the sensors. The variables included are set by the sensor, and the IoE module will record every data point that it receives. The time stamp (DateTime) is provided by the IoE module, and typically, GPS satellites. Measurements represent the time period leading up to the time stamp. The format is YYYYMMDDHHMSS, with the units indicating UTC.
