Sparv embedded

Sparv Embedded is a Swedish company that specializes in the development of miniature embedded sensor electronics. Their miniature radiosonde, named Windsond, is revolutionizing meteorological research. The Windsond has been involved in a variety of research projects including the NASA's IMPACTS project, NOAA's TORUS, and many more.

Windsond is the flagship product of the privately held company Sparv Embedded. Compared to the classic radiosondes, Windsonds do not require the assembly of stationary equipment which allows for mobility in the field. The project's data collection is centered around the Windsond, giving researchers the ability to remain safe by avoiding the tornado's path. Our first Corporate Patron, Sparv Embedded, has given those involved in TILTTING the opportunity to make new discoveries by providing their instrumentation to use for data collection.

The company is based in the Swedish city of Linköping, a technology hub that is home to world famous companies in defence, telecom, UAV and IPTV. A lot of tech companies and startups converge on Mjärdevi Science Park and Linköping University gives a fresh influx of ideas and people. The strong local network helps Sparv Embedded take on assignments of varying sizes. Sparv Embedded is keen to build further industry contacts! They can customize Windsond software and hardware for any project purpose, like TILTTING, and also discuss related projects. Don't hesitate to email Sparv Embedded with any inquiries at

This schematic shows a reusable Windsond in action. Once the sonde is switched on and connected to the laptop collecting the data, it is then launched via a balloon (this is seen in step one). The Windsonds are lifted upwards throughout the atmosphere collecting data (as seen in step two) and continues to rise until the balloon either bursts or the researchers are ready to end data collection. (In step three) When the researchers are ready to end the data collection, the Windsond has a mechanism that will cut the string off from the balloon and allow the Windsond to float gently back down to the surface. Once the Windsond is on the ground, it will play a chime so it can easily be located and used again (as seen in step four).

Everything required to launch a Windsond is in the picture seen here:

  • 3 Windsonds

  • Balloons

  • A Receiver and USB connection

  • USB lithium-ion battery charger

Once you have the Windsond software installed on a laptop, grab some helium and hit the road!
