MH Z14A CO2-Sensor

MHZ14 and MHZ19 CO2 Sensors • Wolles Elektronikkiste

20210612· I checked the accuracy of the MHZxx CO2 sensors with the Technoline WL 1030, a commercially available CO2 measuring device. This model was the 2021 winner of the German test institute “Stiftung Warentest” in the category of CO2 measuring instruments. Nevertheless, of course, the question arises as to how exactly it measures itself, especially since, if you look at the functionality and ...

Setting up the MHZ14A CO2 sensor with Raspberry Pi ...

20200517· So I bought an an MHZ14A sensor to get CO2levels at home, by attaching it to a Raspberry Pi 3. Indoor CO2levels have pretty large impact on sleep and concentration. Usually measured in ppm (parts per million), the desired values are below 1000ppm. CO2 levels and effects source. PPM Effects; 250400: normal outdoor air level : 400 1000: indoor, good airflow: 10002000: …
