CO2 sensor - MH-Z1311A, 0-2000 ppm

Finally! We have replacement for MH-Z14A! This is also NDIR CO2 sensor, working in range 0-2000ppm. It has UART interface and what is important - it has basically the same communication protocol.

That means, You can connect to our NAM sensors and start monitoring CO2 levels right away. Just use handy PCB adapter for CO2 sensor, solder MH-Z1311A module, some goldpin and short F-F cables. Then just enable MH-Z14A in NAM config and ready to go!

MH-Z1311A has no reverse polarity protection. Mistake with swapping Vcc and GND will destroy sensor. Double check before powering on!

Connecting to NAM:
