If you have ever wondered what the air quality is around living or work space, a new Instructables has been published that enables you to create a handy DIY Arduino air pollution monitor.
The Arduino air pollution system focuses on measuring the components of the Environmental Protection Agency’s Air Quality Index that includes : ozone, particulate matter, carbon monoxide, sulphur dioxide, and nitrous oxide.
“We have yet to fully calibrate our device, but we have extracted data from sensor data sheets to make some preliminary estimations. The sensors used are relatively inexpensive and vary greatly from component to component so they need to be calibrated with known concentrations of the target gasses. We have not yet had the opportunity do so.
This device detects all of these pollutants except sulfur dioxide. The device also includes a town gas sensor to alert the user to gas leaks or the presence of flammable gases. Furthermore, a temperature and humidity sensor is included as these conditions can impact the performance of the gas sensors.”
Full instructions on how to build your very own DIY Arduino air pollution monitor have been kindly published to the Thingyverse website and can be accessed via the link below.
