There have already been quite often told about the mhz19 sensor and about esp8266, as well as not forgetting to mention the mqtt protocol. I read all this and decided to combine the read in one device. Actually in the picture this is it. Entry (skip) I have been registered on Habré for quite some time and I read it even more, but I am not particularly active, but I must say that I learned a ...

Nice article on testing out the Z19 on a Raspberry Pi. Update 15 OCT 2020: Just found a fairly officiallooking Arduino library for the MHZ19 here by WifWaf. In that repo they have some nice notes about calibration. The Z19 allows us to turn autocalibration off (which seems useful otherwise it is using the lowest reading in a 24 hour period as ''400 ppm''). Would be good to experiment with ...
