How to Measure Co2 - Setup and Code a MQ135 CO2 Sensor

Hi All, today, im showing you how to setup and Code a MQ135 CO2 Sensor this will give an estimated measure of the PPM (parts per million) in the air.

I am using the MQ135 CO2 Sensor along side with a Arduino Mega but you can use any board you like as long as it has analogue inputs.

This sensor is designed to be used in my Algae Co2 Scrubber check out those videos as well
