May 27, 2021· The data from the MQ135 Sensor is taken from the analog pin of the MQ135 which is connected with A0 of the Arduino and is stored in variable anInput. After uploading the code to the Arduino we will get the concentration of the carbon dioxide. You will see the CO2 Level on the OLED display module in the PPM value.
For smaller volumes, sensor manufacturers and the gas industry measure CO2 and other trace gases in parts per million. For example, % CO2 is equal to 400 parts per million, which is commonly abbreviated as "400 ppm". Indoor Air Quality 10,000ppm CO2. When talking about indoor air, partspermillion makes sense.

The CO2 Alarm is a wall mounted, stand alone carbon dioxide alarm. It has two thresholds which can be preconfigured to switch the two on board alarm relays at any required level of carbon dioxide up to 10,000 ppm. Control and alarm threshold levels may vary. At Duomo we can configure the switching points to suit your personal preference.
