Sensirion hit the one billion mark on July 8, 2021 with an SCD4x CO2 sensor – a major milestone in what is still a fairly short company history. Almost 23 years ago, Sensirion was established as an off-shoot of the Swiss Federal Institute of Technology (ETH) in Zurich, laying the foundations for the success of this Swiss company. In just a few years, the sensor manufacturer established itself as the market leader in the field of humidity and temperature sensor technology.

Approximately 80% of the sensors produced to date come from humidity and temperature sensor technology. In addition, Sensirion has also expanded its product portfolio in recent years and now offers sensor solutions in various markets that enable new applications or solve problems in existing applications.

So, it is not surprising that the billionth sensor is an SCD4x CO2 sensor. This disruptive sensor solution demonstrates Sensirion’s innovative strength: Sensirion was the first company to successfully launch a miniaturized CO2 sensor for indoor air quality applications. Thanks to a revolutionary measurement principle, the size of the sensor could be reduced sevenfold.

“Our success is based on the outstanding performance of all our employees as well as Sensirion’s unique corporate culture. I am very proud of this milestone and at the same time confident that there will be many more in the future,” said Marc von Waldkirch, CEO of Sensirion AG. “The global trend toward digitalization is making it possible to develop novel solutions that can support people and the environment in more and more areas of daily life. Sensor technology plays a key role here.”
