Air Quality: CO2 Sensor MH-Z14 | MySensors Forum

Nov 17, 2014· MH-Z14A vs MH-Z19 ? Their price is very similar and kinda meh in comparison but which should one prefer and when? ... Hi @Siddharth-Velappan The warmup time of the MH Z19b is 3 minutes. So 2 is probably fine, but you could probably do 3 just in case. Although 2 would save your more battery time. Do you mind explaining your setup a bit more?

CO2-Sensor MH-Z19B - Unsinnsbasis

Nov 10, 2020· Der MH-Z19B ist ein CO2-Sensor, mit dem man eine CO2-Ampel selbst realisieren kann. Durch die Corona-Pandemie (COVID-19) sind zur Messung der Luftqualität in Räumen, die von mehreren Personen gleichzeitig benutzt werden, vermehrt CO2-Sensoren im Einsatz ( in Klassenräumen in Schulen). Der CO2-Wert gibt einen Hinweis darauf, wie „verbraucht” die Luft ist - indirekt wird daraus …

Not inspired with the stability of MH-Z19B sensors. Recently I bought several Carbon Dioxide CO2 sensors and two of them were MH-Z19B. 0-5000ppm works better than 0-2000ppm MH-Z19B sensor. These sensors are cheap and can give you general information about CO2 level. If you want one sensor and want to relay on this sensor only, I'd not recommend ...
