Only with sufficient fresh air, in which our human concentration and performance is fully given, as well as our immune system has the highest protection, the traffic light shines green.
When the air deteriorates, i.e. when oxygen is consumed and carbon dioxide is exhaled with the air we breathe, the traffic light first lights up yellow, then red if it increases further. At this point, at the latest, extensive ventilation is urgently required.
As the air improves, the colors decrease again, indicating the success of the ventilation measures.
An internal light sensor switches the LEDs off in the dark, thus automatically saving energy.

Due to the automatic dimming of the LED lights of our traffic lights at night, the actual power consumption is extremely low and thus also helps to save energy:
0.03 kWh in 24 hours*
(Important: the traffic light should not be disconnected from the power supply at night because the automatic self-calibration is designed for 7 days of continuous operation in order to determine better, more realistic standard values!)
*current measurement as of 08.11.2022
The traffic light is not mounted directly next to the windows on a wall. The height of the traffic light should be high enough to be visible from as many places as possible and at most so that the touch field for resetting the acoustic signal can still be touched comfortably with the hand.
CO2 from breathing air is distributed quite homogeneously in the room. In classrooms, one traffic light is sufficient, a standard gymnasium should be equipped with 2 traffic lights and a Pax400 auditorium perhaps with 3 or 4 traffic lights. This also depends on the room geometry and cannot be expressed in square metres.

The traffic light is suitable for both possibilities; if it is only switched on when the room is in use, one can assume a longer service life.
In order to ensure consistently correct Co2 measurement results, it must be ensured that the Co2 traffic light is exposed to fresh air for at least 30 minutes every 7 days(from year of manufacture 2021) or every 24 hours(before year of manufacture 2021). Simply ventilating the room in which the measuring device is installed is sufficient for this. This leads to a constant self-calibration, thus to the full and accurate functioning of the device.
Basically, you can check the sensor yourself. Simply blow on it calmly for about one minute and observe the colour changes on the traffic light. You can also send us the traffic light for a free factory inspection, during which we may readjust the sensor. If we need to replace the sensor, you will receive a discounted replacement offer, just as with all other gas detectors from our company. Regular or daily draught-ventilation also helps the traffic light to a higher and longer reliability.
