Simple in Use, From Setup to Data Retrieval
The data logger and the accompanying items are designed for ease of use throughout the research process, from setting up the logger, attaching it, to retrieving and analysing the data. The logger is supported by the SeaStar software and the PC communication cable which have to be purchased with the first order.
Setting up the Logger
To launch the temperature data logger for measuring, the end cap of the housing is unscrewed and a USB cable connects directly to a PC computer. In the SeaStar software, the user sets the start time, start date and sampling interval before starting the logger in measurement mode. The logger synchronizes its internal clock with the date & time on the computer being used.
Memory and Battery Life Calculations
The software automatically calculates when memory fills based on certain interval settings, making it easier for the user to decide how to program the tag. Estimation on battery consumption during that time period is also calculated. It is also possible to have the software do memory and battery calculations for a specific measuring period.
Uploading the Data
After recovering the logger, it is connected with the communication cable to the PC and the recorded data is uploaded to the software. The results are displayed both in graphic and tabular form and the data can be exported to other programs. The time series data shows each measurement with its own time stamp.
Low energy consumption
After data retrieval the logger can be restarted or put into sleep mode for later use. Battery life estimation is always reported upon connection with the logger. Due to the low energy consumption circuitry design the battery life is long, but the actual lifetime depends on usage and sampling interval used.
