A climate sensor measures the content of PM2.5 particles (particles smaller than 2.5 µm) in the passenger compartment*.
The content of contaminants outside the car is measured by an external service and is based on official data.
To be able to use this app, the following is required:
- The car must have access to the network for at least 1 minute when the app is started or the car is restarted.
- The car must be running in order for the PM2.5 sensor to take measurements.
