City life requires a conscious approach to room ventilation. Lack of oxygen and excessive levels of carbon dioxide can negatively affect both health and daily work. In order to keep the situation under control, it is worth installing a weather station with a Discovery Report WA40 CO₂ sensor in the room. This device evaluates the CO₂ level in real time and signals when the critical value is reached.

It also displays the time, measures temperature and humidity. The data is displayed on a built-in color display, the brightness of which can be adjusted (3 levels available). The projected values ​​are large and clearly readable even from a distance. The device works with a built-in battery and can be charged with a micro-USB cable.
