Sensirion is a leading manufacturer of environmental sensors for measuring and monitoring various air quality parameters such as CO₂. We recently launched the SCD4x, the world's smallest CO₂ sensor.

Take a guess and answer the question about our CO₂ sensors below. With a little luck, you win a Sensirion CO₂ monitor that can be used to improve your air quality.

Sensirion's newest CO₂ sensor - the SCD4x - is the world's smallest CO₂ sensor. By what factor is it smaller than its predecessor, the SCD30?

The participant who has estimated the correct factor closest wins a Sensirion CO₂ monitor. If several participants guess the correct value, the prize will be drawn. One Prize will be given per trade show. 

To participate, answer the question and submit the answer form electronically. The winner will be notified by e-mail after the trade fair. Good luck!

Environmental conditions have a strong impact on our well-being, comfort and productivity. Sensirion's sensor solutions provide detailed and reliable data on key environmental indicators and open up new opportunities for the development of smart devices to monitor and improve indoor air quality. The product range of our environmental sensors includes various CO₂ sensors.

CO₂ content is an important indicator for minimizing the risk of infection with bacteria and viruses, such as COVID-19, in indoor environments. CO₂ correlates with the tiny droplets (called aerosols) emitted not only when coughing or sneezing, but also during normal breathing and talking, and can potentially contain viruses. This means that if the CO₂ concentration in the air is high, then the number of aerosols is also high and action is required.
