• viruses or other pathogens There is a large number of diseases or pathogens and in particular disease-causing viruses which spread through the air and in particular through aerosols and thus in the air as aerosol particles present. It is therefore desirable to be able to detect such viruses in the air and to be able to warn of their presence when predetermined limit values are exceeded.
• the limit values can be concentrations of the particles in the air, for example, from which an infection of a person becomes increasingly likely.
• warning devices such as fire or smoke detectors
• these are not suitable for detecting potential pathogens present as particles in the air and for comprehensively informing people who are affected by the warning.

• the particles against which a warning is to be given can preferably be fragmented by vibrations so that they can be broken up.
• the alarm device has a sensor unit which is designed to detect a concentration of vibration-fragmentable and in particular organic particles with a specific target diameter in the air by determining a difference between a first light scatter on a first sample of the air and a second light scatter on a second sample to determine the air.

• the limit value is, for example, the value of the concentration at which an infection with the pathogen or the virus becomes possible.
• several limit values can also be stored, in which case a warning can then be given when each limit value is reached.
• the particles or the organic particles can be understood in simplified terms as a body which can be made to oscillate.
• a body with a spherical shell. If the particle vibrates strongly enough, this shell or particle will break apart, allowing the pathogen to be deactivated and the particle to be 'cracked' or fragmented into smaller pieces.
• the oscillation or the strength of the oscillation is dependent, for example, on the wavelength of a light exciting the oscillation and the intensity of the light as well as on an irradiation duration or a pulsing.
• the particle can also be made to vibrate, for example, by applying ultrasound to the particle, with the vibration being dependent in particular on the frequency of the ultrasound, which can also lead to vibration fragmenting the particles.
• the vibration By adjusting the wavelength of the light and/or the frequency of the ultrasound to a value determined by the respective type of particle and its diameter In this dependent resonance range, such an effect can be amplified or achieved with a comparatively low use of energy, since less energy has to be expended to “destroy” or break up the particles.
• a destroyed particle comprising several parts, which previously had a diameter corresponding to the target diameter, has changed light scattering properties compared to the whole particle, since the light is no longer scattered by a single particle but by its smaller individual parts or fragments.
• a concentration of the particles in the air from which the samples were taken can be determined based on a difference between the first light scatter on the first sample with fragmented particles and the second light scatter on the second sample with non-fragmented particles.
• the sensor unit can determine the concentration at regular time intervals, depending on previously determined concentrations, or continuously.

• the reaching of the limit value and/or the concentration of all suitable signals within a transmission range of the transmission unit at the time of transmission can be determined, particularly when using reporting units that are designed for wireless signal transmission radio receiver located, and in particular especially when using beacons as a reporting unit or as part of the reporting unit, the following behavior or scenarios are implemented:
• the beacon broadcasts a UUID that is unique to the associated alerter. However, transmission is only carried out if or as long as the limit value is exceeded, i.e. discontinuously.
• an application or app on an internet-enabled (“smart”) device that checks the device’s environment for such beacons using a Bluetooth module on the device. If corresponding advertising packages or general signals or messages are received from a beacon, the app issues a warning.
• the signal or message transmitted by the beacon is in a format that also contains a "beacon code" containing the status of the alerter and in particular the concentration, or a URL associated with the alerter's beacon in addition to or as an alternative to a UUID.
• the beacon sends continuously or continuously and the "beacon code" or the URL can display the status of the sensor unit in or via the app, which can be stored in a server, for example, to which the alarm device sends the corresponding information can transmit. It is advantageous here that even if the threshold value has not been exceeded, the sensor unit or the warning device or its state can be detected, so that a functional check of the warning device is possible that is independent of whether the limit value has been reached.
• the beacon may have a UUID specific to that beacon. This could be registered centrally on a server together with its location, which means that the sensor units can be displayed in a corresponding map application. If a terminal device registers an exceeded threshold value of a sensor unit through a message from a beacon, it sends their UUID to the server, which then displays the sensor unit differently in the map and can thus warn viewers of the map. The sensor unit then does not necessarily need its own connection to the server or its own Internet connection, because the relayed devices would implement the forwarding as an intermediate station with the respective existing application or app.
• the beacon can also be designed not only as a transmitter unit but also as a receiver unit, ie as a transceiver. In addition to the aforementioned variants, it can therefore be provided with such a transceiver that the transceiver or the receiving unit continuously monitors its surroundings for other transmitters, i.e. smart devices with Bluetooth, these transmit a respective UUID that uniquely identifies the smart device and the beacon or the alerter store these UUIDs preferably anonymously for a predetermined period of time.
