The sensor is designed for indoor air quality testing. The main gas detected is carbon monoxide, alcohol, acetone, thinner, formaldehyde and other slightly toxic gases.
This sensor is designed for comprehensive monitor over indoor air condition. It's responsive to a wide scope of harmful gases, as carbon monixide, alcohol, acetone, thinner, formaldehyde and so on. Due to the measuring mechanism, this sensor can not output specific data to describe target gases' concentrations quantitatively. But it's still competent enough to be used in applications that require only qualitative results, like auto refresher sprayers and auto air cycling systems.
As described in Introduction, this sensor does better in providing qualitative results over a wide scope of target gases. In this demo, we difine 4 statuses for reference in the .cpp file. They are:
We encapsulated the judge structure in .cpp file. You can find your way to modify the threholds in it.
