Embodiment Construction

[0044] figure 1 is a block diagram showing a portable air quality sensing device according to a first embodiment of the present invention.

[0045] exist figure 1 , reference numeral 100 denotes a casing, such as a casing of a smart phone, in which an environmental parameter detection device in the form of an optical particle concentration detection device 10 is disposed, which is configured to perform a time-controlled measurement operation and / or a reading of the instantaneous particle concentration for which a predetermined particle is detected in an event-controlled measurement operation. In this embodiment, the particles are PM2.5 fine dust particles.

[0046] The particle concentration detection device 10 has an optical emitter device LD for guiding the optical measurement beam OB through the optical exit area OF to the outside of the housing 100 into the focus area FA. Particles P can be detected in the focus range FA. Also arranged within the housing 100 is an op...

Abstract

The present invention provides a portable air quality sensing device and a corresponding air quality sensing method. The portable air quality sensing device is equipped with environmental parameter detecting means (10) configured to detect local readings of one or more environmental parameters affecting air quality; retrieval means (150) for retrieving at least one global AQI value and / or at leastone global measurement of an environmental parameter affecting air quality contributing to the global AQI value from at least one remote reading data source means (200) via a network (500); and an evaluation device (20) configured to form a local AQI value based on said one or more detected local readings and said at least one global AQI value and / or on said at least one retrieved global reading.

Description

technical field [0001] The present invention relates to a portable air quality sensing device and a corresponding air quality sensing method. [0002] Although applicable to any air quality sensing device, the present invention and its potential problems are described with respect to an air quality sensing device integrated in a mobile device. Background technique [0003] Air pollution from suspended particulate matter, especially PM2.5 fine dust or P10 fine dust, and toxic gases is one of the world's most serious health threats and a cause of many premature deaths. Poor air quality is especially dangerous for children, the elderly and the sick. [0004] Air quality is determined by a number of limits or guideline values ​​stipulated in laws or regulations. Air quality monitoring is typically performed at monitoring stations located, for example, on busy roads or in landscaped areas. [0005] Many countries have defined scalar air quality indices, also known as AQI value...
