Measuring CO2 Concentration using Arduino and MQ-135 Sensor

This project looks into designing and testing a CO2 sensor using an Arduino UNO. An MQ-135 sensor is tested under different conditions in order to obtain detection limits and measure trends. The literature shows that there is around 400 PPM of carbon dioxide in the atmosphere, the average indoor values range from 35-450 PPM and the maximum acceptable level is around 1000 PPM. The MQ-135 ...

IoT Based Air Quality Index Monitoring with ESP8266 & MQ135

08/05/2020· MQ135 Air Quality Sensor. The MQ-135 gas sensor senses the gases like ammonia nitrogen, oxygen, alcohols, aromatic compounds, sulfide and MQ-3 gas sensor has a lower conductivity to clean the air as a gas sensing material. In the atmosphere, we can find polluting gases, but the conductivity of the gas sensor increases as the concentration of polluting gas increases.

How to calibrate an MQ-135 gas sensor (CO2) - Sensors ...

06/05/2021· If you have a tank of Nitrogen or Oxygen, you can use that to get a reading for zero CO2. A quick scan of the datasheet for the MQ135 shows that it responds to a lot of gases. If someone farts nearby, it will detect it and you can't tell which gas it was. Actual CO2 sensors cost $80-$400 for the cheap ones. Thanks for your help.
