    • RE: MH-Z19 CO2 sensor

      I know I'm resurrecting an ancient topic here...

      How have these sensors worked? I need the ability to monitor CO2 and evacuate it when it get's too high. This isn't super mission critical stuff here but I would like to use a sensor like this to get a better idea of how much air I need to evacuate.

      I'm looking at building something to interface with a MQTT broker to control other IoT devices on my hub. How hard would it be to add that capability to an arduino type solution like this one here?

      I'm more familiar with RPi's but am interested in this because of the "simplicity".

      Thanks!

      Cheers,

      Joe
