NO2 sensor design with KNMI


We have had the pleasure to be visited by KNMI (Royal Netherlands Meteorological Institute) representatives this week for a workshop on developing their novel NO2 sensor. We had a very productive workshop on practical design, measurement principles, project planning and also touching on eventual business ventures.

NO2 (Nitrogen dioxide) has a strong negative health effect. Due to a degradation time measured in minutes or hours and the low background levels, NO2 is a clear indicator of nearby pollution. The gas is almost exclusively produced from combustion, making the sources easy to pinpoint. This makes sampling NO2 suitable to make detailed maps of urban pollution.

With a resolution around 1 ppb and response time 1 second, the KNMI NO2 sensor has a unique level of performance considering the weight and price. Once fully developed, this will enable mobile measurements of this important gas.

Sparv’s thoughts on sensor commercialization

Here is our overview of the work needed to develop a sensor from idea to product. The text is based on the experience of Sparv Embedded, but is valid for any project.

Path to sensor commercialization

Please get back to us if you have any thoughts or inputs.


Sorry for not updating this blog too often.

We will be out of the office most of the time between December 21st – January 2nd. We will get back to you as fast as we can. We hope all of you will have a wonderful Christmas and a happy new year!

Swarmsonde is in the news

Swarmsonde launch

Researchers from Penn State University used Sparv’s novel instrument “Swarmsonde” for a research project earlier this year. The purpose was to capture thermodynamic data within and around a tornado. The data obtained will help explain how tornadoes are formed. This new instrument can measure up to 32 sondes at the same time and stay in the air for more than an hour. Click on Swarmsonde for specifications about the sounding tool.
