Website Questions / MQ-135 Air Pollution Sensor
« on: July 21, 2011, 04:39:12 AM »
Hi,

First I'm very grateful about the clear and easyread information in this website.

Second, I wish to ask how can I understand data from MS-135.
I conect my MS-135 in the same way as I see in http://wiring.org.co/learning/basics/airqualitymq135.html
And I get data between 77 and 80. I don't know how to convert this data to PPM or % of CO2.

Thanks you

Bernard
