Neue Einsatzgebiete für Kohlendioxidsensoren verlangen nach immer kleineren und mobilen Systemen. Beispielsweise hat sich in neuerer Zeit herausgestellt, dass sich in abgeschlossenen Räumen schnell eine Kohlendioxidkonzentration bilden kann, welche den MAK-Wert (MAK = „maximale Arbeitsplatzkonzentration") deutlich überschreitet. Beispiele hierfür sind Besprechungsräume, Autoinnenräume oder Räume mit mobilen Gasöfen. Zudem werden bei Neubauten Räume immer dichter isoliert, was zu einer schlechteren Durchlüftung und damit zu einer höheren Kohlendioxidkonzentration führen kann.New Fields of application for Carbon dioxide sensors demand ever smaller and mobile systems. For example, it has recently been found out that in enclosed spaces quickly can form a carbon dioxide concentration which is the MAK value (MAK = "maximum Occupational Exposure ") clearly exceeds. Examples of this are meeting rooms, Car interiors or Rooms with mobile gas stoves. In addition, new buildings become spaces getting denser isolated, resulting in poorer aeration and thus to a higher one Lead carbon dioxide concentration can.
Die Erfindung umfasst einen mobil einsetzbaren Kohlendioxidsensor ohne eine stationäre Versorgungsspannung, welcher sich zum Einbau z.B. in Mobiltelefonen, Kugelschreibern, Laserpointern, Laptops, Pocket-PC's, Taschenlampen oder Schlüsselanhängern eignet.The invention includes a mobile insertion Baren carbon dioxide sensor without a stationary supply voltage, which is suitable for installation in mobile phones, pens, laser pointers, laptops, Pocket PC's, flashlights or key fobs.
