Embodiment Construction

[0032] In the following description of an advantageous exemplary embodiment of the invention, the same or similar reference symbols are used for elements that are shown in different figures and have a similar effect, a repeated description of these elements being omitted.

[0033] figure 1 A block diagram of a device 100 for determining the carbon dioxide content of ambient air according to one embodiment of the invention is shown. The device 100 , which can also be referred to as a carbon dioxide measuring system, for example, includes a mobile data transfer device 110 . The mobile data transfer device 110 is, for example, a mobile phone or a tablet computer. A sensor 120 for detecting carbon dioxide in the ambient air 130 is integrated in the mobile data transmission device 110 . For example, the sensor 120 can have an intake channel 140 in order to draw in or generally receive ambient air 130 and also have an exhaust channel 150 in order to conduct analyzed (ambient) air ...

Abstract

The invention relates to a method (200) for determining the carbon dioxide content in ambient air (130). Said method (200) comprises the following steps; a mobile data transmission device (110) which comprises a sensor (120) for detecting carbon dioxide in ambient air (130) is provided (210); and the sensor (120) is calibrated (215), said calibration step (215) measures the carbon dioxide content of the ambient air (130) in a reference situation (300). The method (200) also comprises the step of measuring (220) the carbon dioxide content of the ambient air (130) using the sensor (120).

Description

technical field [0001] The invention relates to a method for determining the carbon dioxide content of ambient air, a corresponding device and a corresponding computer program. Background technique [0002] CO 2 The main applications of sensors are in ventilation and air conditioning technology for the required control of ventilation installations (see for example the Carbocap sensor at www.vaisala.de) and in safety technology, e.g. for monitoring CO 2 Airtightness of running counter facilities or fermentation cellars or cooling facilities. [0003] Typical CO 2 The content is between 380ppm and several thousand ppm in the air; according to DIN EN 13779, there are four quality levels: below 800ppm is good, at 800 and 1400ppm (0.08 to 0.14 volume percent) is medium and moderate quality, above 1400ppm is low space air quality; the maximum injection concentration (MIK) is 3000ppm (0.3%), and the maximum workplace concentration for daily exposure of eight hours per day is 500...
