[0030] Vibration motor 11 can be electromechanical or electromagnetic.

[0031] The main function of the mobile device for determining the level of carbon dioxide is the prompt analysis of air for the concentration of carbon dioxide in the room and the issuance of notifications about excess concentration of carbon dioxide.

[0032] The mobile device for determining the level of carbon dioxide is used as follows.

[0033] The mobile device for determining the level of carbon dioxide is switched on by means of control elements 3, after which power is supplied to the control board 6 from the power source 8.

Also, a message about the excess of the carbon dioxide level is displayed in the smartphone application. Then the user decides to leave the danger zone with a high level of carbon dioxide, or ensures an influx of fresh air.

[0039] When the carbon dioxide level is normalized, the device stops issuing notifications about high carbon dioxide levels, a message about normal carbon dioxide levels is displayed on display 2, which is duplicated in the application on the smartphone. It is possible to configure notifications using control element 3, these settings are stored in the permanent memory of the control board 6, then there may be notification options - a message on display 2 and an alarm signal on speaker 10 or a message on display 2 and vibration of the vibration motor I.
