Problem with Infrared CO2 sensor (SEN0219)
![userHead](https://dfimg.dfrobot.com/dfPortrait2.png)
I've bought SEN0219 and i'm using Arduino Uno. I got sample code from wiki.
It gives reasonable 300-500 ppm values at start but after couple minutes it raises to 2500-3000 ppm and i'm hard to believe that i dfrobot in that conditions with air condition.
It seems that after preheating time (around 3 minutes) it raises to that level, but that can't be correct value. What should i do?
