Carbon dioxide in high concentrations negatively affects our well-being. You feel lethargic, it becomes harder to concentrate, and you may get a headache or even a migraine. If the situation is out of control for a long time, you could begin to feel lethargic or might experience other symptoms of chronic fatigue syndrome. All it takes is to forget to air the room out in time. The Levenhuk Wezzer Air PRO DM20 is an instrument designed specifically to monitor the CO2 levels, thereby making you feel more comfortable.

The Levenhuk Wezzer Air PRO DM20 Air Quality Monitor is a “smart” CO2 monitor that can be set up via the Smart Life/Tuya Smart mobile app. The connection is established via Wi-Fi. The device alerts you to the CO2 level by changing the color of the backlight: green – excellent, yellow – the situation requires attention, and red – you need to take immediate action. As soon as the CO2 level becomes critical, the device will emit a beep to alert you.

The air quality monitor is powered by a rechargeable battery.

Please note: An AC adapter (not included) is required to charge the device. The USB port voltage of the PC is not sufficient for this purpose. You can also use a smartphone charger.
