Is it possible to connect any MQ analog+digital sensors?


I am very interested in adding CO readings to my box but the only ones I have at hand are not I2C, they have A0 - D0 - GND - VCC.

Is it possible to use them? I am thinking specifically of the MQ-9, which seems to detect Methane, Propane and CO.

Any ideas? I couldn’t find anything on the topic :thinking:

Unfortunately I am not aware of any I2C CO2 module.

What about using non-i2c components in the diy pro? Is that possible somehow?
