Jun 10, 2019· Carbon Dioxide Sensor MH-Z19b - Part 1 - Hardware design. Some time ago I have purchased online carbon dioxide (CO2) sensor module MH-Z19b. It’s a cheap and very simple sensor with the UART interface allowing concentration measurement in the range up to 5000ppm. The normal level of CO2 concentration is considered about 400-1000ppm.
May 26, 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.
