Advanced research

Senseair has a massive experience accumulated from 30 years in a world leading position within low-cost infra-red gas sensing. We have an experienced research group with doctors active in spectroscopy, electronics, optics, material science, electronics, production technology and micro engineering. We also have several important families of patents, knowledge and IPs within infra-red gas sensing that our customers benefit from. Further on, we have well equipped lab facilities for optical, spectroscopic and electrical science.

We have close collaboration with universities active both as users of our novel sensors and as suppliers of novel sub components for infra-red gas sensors. We do also co-supervise several Ph.D. students at Swedish universities in order to be up to date with the most recent technology.

A research project is normally paid per work hour, and divided in sub-projects ranging between one and three years. How the cost is shared depends on the strategic value for Senseair as well as for the research partners. Sometimes the projects are co-funded by governments or other research funds.  



An organization in the USA is striving to improve acceptance of alco-lock sensors. Since before they have had a close cooperation with Senseair as well as other Swedish companies within the field of automotive safety. One key issue is to improve the detection limit of the sensor in order to minimize the inconvenience of the driver. 

A one-year project was formed with the goal to improve the resolution of the sensor by adjusting the optical setup, trimming the signal chain, improving signal stabilization and switching key components. The budget for Senseair was 900 000 USD, and the project was closely coordinated with other partners that also improved driver convenience.   

The project is carried out in close cooperation with the financing organization, resulting in three times improvement of the detection limit. Scientists from the research department and sub-contractors are involved, as well as hardware-, software and test engineers. Also close collaboration with several sub suppliers is required in order to get maximum gain from each critical sub-component. In-house designed optical test equipment has to be built and shipped to sub suppliers for process optimization. As of now 200 sensor prototypes have been produced and shipped to the funding partner for further evaluation and field tests in the USA. 

The project also presented a pre-study showing how to further gain three times more as well as the estimated effort to reach that. A new one-year research project with new goals and a new budget was formed. 

This sensor can now be found under our breath sensing product Sober Workplace and Sober Transportations. More about the research under over Driver / Sensor inVehicle
