Oct 05, 2020· I also got a MH-Z19B CO2 meter for testing to monitor the indoor CO2 levels. The initial feeling is that it does what it should. In general I have pretty good wifi coverage with a few Unifi access points. One of the sensors is in a building some 25 meters from the house where the wifi is not that strong, but the NodeMCU has no problem with this.
