The levels of CO2 in the air and potential health problems are:
400 ppm: average outdoor air level.
400–1,000 ppm: typical level found in occupied spaces with good air exchange.
1,000–2,000 ppm: level associated with complaints of drowsiness and poor air.
Poor air quality can lead to many negative health effects as well as can cause tiredness, headaches, loss of concentration, increased heart rate and so on. Monitoring the quality of the air may actually be more important than you realize.
In this video, I will use the MQ135 gas sensor to measure the concentration of carbon dioxide in the air using air quality sensor and a NodeMCU dispalying Data on a OLED display, Also we will see how to Code a MQ135 CO2 Sensor which will give an estimated measure of the PPM (parts per million) in the air.
I am using the MQ135 CO2 Sensor( CO2 detector) along side with a OLED Display but you can use any MCU board you like as long as it has analogue inputs.
I have shared the link to the code for this project in the description .
