Air Quality Monitoring with MQ135 and Cayenne


Ok, thank you so much.


This is a really cool idea. Is there a project where we can measure all the ingredients in the air e.g. oxygen, co2, methane, nitrogen, etc. so that the air quality in a specific area can be assessed. Unless this has already been done, I would really like to start working on such a project.


for measuring all the parameter of air, you will need sensors to measure each. Once you have done that you can send each sensor data to cayenne.
