Keep an eye on the air quality Versatile sensor for improved well-being The high-quality and reliable CO2 sensor measures the CO2 content in ppm. In addition to the CO2 levels, the sensor also records the temperature and humidity in the room. The measured values for the air in the room can be viewed at any time via the Homematic IP app. LED display as CO2 indicator The five integrated LEDs indicate the CO2 levels directly on the device. One illuminated LED indicates very good air quality, whereas all five illuminated LEDs indicate a very high CO2 value. Regular, extensive ventilation can counteract the high CO2 levels. In addition, it is possible to switch on a light automatically as a warning from a defined CO2 value, for example, via a freely definable switching threshold. https://elecena.pl/product/19009144/155592a0-co2-sensor-230-v 2021-07-07 https://elecena.pl/product/19009144/155592a0-co2-sensor-230-v 2026-06-29
