CO2 Monitor And Traffic Lights For Offices And Companies

Safe and healthy work spaces need good indoor air


Timely Ventilation Of The Office Space Protects Your Employees

RYSTA transparently shows when it is time to ventilate. This improves the air quality and reduces the risk of virus transmission.

Assurance that the office space is safe and will remain open permanently

Clarity about when and how long the office space needs to be ventilated

Reduction of heat loss through optimised ventilation, especially in the cold months

People work better in good air. Good air also counteracts allergies and diseases.

RYSTA Protect, The Inexpensive Alternative To Air Filters

CO2 traffic light sensors are an affordable alternative to air filters.


The air quality and the air exchange in an office vary from room to room. RYSTA Protect provides individual measured values for the air quality of each individual room. In this way, the indoor climate can be improved in a targeted manner.



RYSTA sensors contribute to sustainability. Thanks to optimised ventilation, especially in the cold months, the office space loses less heat. Nevertheless, the indoor air is significantly improved without anyone having to freeze.


With the help of the RYSTA dashboards, you can see whether the windows are open or the heating is on. This allows you to intervene to avoid unnecessary heat loss.

CO2 And Air Quality

The CO2 concentration provides information about the air quality in closed rooms. The more CO2 there is, the more used the air. This affects the ability to concentrate. A high level of CO2 also means a potentially higher viral load in the air.

If there is an infected person in the room, the virus spreads via aerosols. As the CO2 content rises, the risk of infection increases (if an infected person is in the room).


Better Ventilation, Increased Safety

If the room is ventilated regularly and at the right time, the risk of virus transmission can be significantly reduced. Ventilation also contributes to a healthier, more productive indoor climate.


The CO2 traffic light is a visual warning system that informs everyone in the room when it is time to ventilate. Other measured values, such as temperature and humidity, are displayed on the dashboard.

Benefits Of The Sensor

The CO2 traffic light is a discrete warning system that is attached to the wall. It indicates the CO2 concentration and is developed specifically for work environments.

Data for each room and the entire building can be viewed on a web based dashboard.


Easy installation: The sensors can be easily installed in existing and new buildings. You can visualise the air in rooms within seconds.

Each Sensor Measures

Each sensor measures CO2 concentration, air temperature, humidity, air pressure, noise and brightness.

The CO2 traffic light on the sensor indicates CO2 concentration.

Other climate values can be viewed on the dashboard.
