Reduce the risk of virus infection
What is it about?
- CO2 is emitted by humans as they breathe. The higher the CO2 concentration in a room, the higher the proportion of exhaled air that is inhaled again several times and can potentially be contaminated with viruses and bacteria.
- Infections that spread via aerosols and droplets can be contained by better ventilation, or the number of new infections can be reduced.
- At higher CO2 levels, the ability to concentrate and general performance also suffers.
- The use of CO2 traffic lights promotes sufficient ventilation and regulates excessive ventilation. Especially in the winter months, this helps to avoid low temperatures in the classrooms.

Please note: The Sensirion CO2 monitor was only given away as part of a Sensirion donation campaign and is not available in stores.
The traffic light comes already calibrated and only needs to be connected to electricity. The LED display can be used immediately for CO2 monitoring.
Whenever possible, place the traffic lights at eye level and not directly next to windows or people.
We recommend to ventilate the lights already when the display is red. Ventilate the room until the traffic light indicator has gone back to green.

As long as the traffic light is connected to the electricity, it stores a CO2 value every 5 minutes. The storage space is sufficient for the CO2 values of about one month.
With Sensirion's MyAmbience CO2 App, live values and the stored values can be downloaded from the CO2 traffic light and displayed on the smartphone.
Efficient Ventilation to Reduce Virus Infection
Pupils are back in schools all over the world. Despite the coronavirus pandemic, they are sitting side by side in closed rooms for several hours. Of course, this raises concerns about virus transmission.
Tiny droplets (known as aerosols) are emitted not only when people cough or sneeze, but also during normal breathing and speech. These aerosols may contain viruses, which is why frequent and effective ventilation is more important than ever. The more fresh air there is in a closed room, the less exhaled air which may contain viruses.
