AIR QUALITY ALERT SYSTEM AND METHOD
First Claim
Patent Images
1. A system, comprising:
- an input for receiving a first air quality indication for a first area;
a proximity sensing arrangement for determining if a user is in the proximity of a door or window between the first area and a second area;
an output for providing a recommendation for a status of the door or window; and
a processor,wherein the processor is adapted to process the first air quality indication and a signal from the proximity sensing arrangement, and to control the output accordingly;
wherein, the system further comprising an input for receiving an indication of a second air quality for the second area, andwherein the processor is adapted to control the output based on a difference between the first air quality indication and the second air quality indication.

Abstract
An air quality alert system provides a signal which indicates whether or not a door or window should be (fully or partially) opened or closed. The system takes account of the air quality in a first area (e.g. outdoors) as well as the proximity of the user to a door or window so that information is only provided when the user is situated at the door or window. This avoids overloading the user with unwanted information.
