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 MH-Z19B, unless you have other reliable …
