DST nano-T: World's smallest data logger!

DST nano-TD available in spring 2011

Star-Oddi recently launched the DST nano-T which is the world's smallest temperature data logger. It was designed to be an implantable temperature logger for small animals. DST nano-T is made of biocompatible materials, alumina and biocompatible epoxy, and its size and shape makes it ideal for implantation in small animals. The logger is only 6mmx17mm and weighs just 1gr. It is programmed to measure temperature from 0-45°C and the temperature accuracy is +/-0.2°C. It holds up to 5248 measurements and the battery lasts for up to 12 months.

Recorded data is stored in the logger‘s internal memory with a real time clock reference for each measurement. After retrieving the data, the DST nano-T can be re-programmed and reused as long as the battery lasts. The DST nano-T is supported by the SeaStar software and a communication box which serves as an interface between the logger and a PC. Communication between the logger and the communication box is wireless. In the software, the user sets the start time, start date and sampling interval before starting the recorder. Up to seven different intervals can be set for the same measurement sequence. This is especially useful when more frequent measurements are needed at a certain time period. After recovering the logger recorded data is uploaded in the supporting software where results are displayed both in graphic and tabular form.

With its waterproof housing and carefully chosen materials the DST nano-T can be used for collecting temperature data underwater. It is suitable for the tagging of small fish and animals and any use where ultra small and lightweight temperature recorder is required.

Northern lights

The geographical position of Iceland near the Arctic Circle makes it the ideal location to experience the magnificent display of aurora borealis or northern lights. The lights, which are also called polar auroras, are most clearly visible between 65 and 72 degrees on the northern and the southern latitudes. The auroras on the southern hemisphere are usually referred to as southern lights or aurora australis.

The northern lights are formed when highly charged particles from the sun collide with atmospheric molecules in about 100-250 km height from the earth. The earth’s magnetic field repels most of the particles which causes them to flow around the earth until they reach the two poles where a small portion of the particles manages to slip inside the atmosphere.

As the mystery behind the phenomenon has only recently been solved, many beliefs and superstitions have been created around the northern lights through the centuries. Most common belief is that this happens due to the cold air during the winter months, which is the time of year that the northern lights can be witnessed.

Because of its seemingly endless winter nights Iceland has become a popular destination among Japanese newly-weds for a honeymoon destination. According to Japanese believes a child who’s conceived under the northern lights will be highly intelligent.

In Iceland pregnant women were advised from looking at the lights as it was believed that the child would be born cross eyed.


Last October Star-Oddi launched the graphic data analysis software PatternFinder.

In PatternFinder the user can import and analyze large amounts of recorded data from Star-Oddi loggers and any other type of data in text file format.

The main goal of PatternFinder is to make data analysis faster, more efficient and easier.

PatternFinder case studies will be presented soon.
