· If you have not read the previous article, the Winsen MH-Z19 sensor is more accurate than the MQ135 environmental sensor. It is much more expensive (about $24 / 20€) but measuring the CO2 level does not require a “hack” value expressed in ppm is retrieved directly from the PWM pin or from the serial port.

It’s nice to have the air quality data into your Home Automation platform. But that’s not the goal. But we ...
MH-Z19 contains power-hungry incandescent light bulb as IR emitter and it pulses to make measurements. My Esp-01 + MH-Z19 consumes 70mA when not measuring and 250mA during IR pulse. It makes these pulses (measurements) every 5 seconds when powered. Also, it calibrates upon startup for maybe 10-20 seconds, so I power it from USB or power bank, if I need mobility. By the way, logic …
