<![CDATA[Mq135 Air quality limits]]>Hello, I'm new here.
I'm using mq135 with arduino, to measure the quality of the air inside.
I have had readings between 45 and 150.
What are the limits? For example :
0-50, good
51-100, regular
101-199, it's not good
200-299, very bad
300-399, terrible

400, critic

Is this table correct?
