I noticed yesterday that my readings were oddly static. I fiddled with calibration settings and now it reports 0 for 2.5. See the attached photo.
If anyone has any ideas please let me know!
Thanks!
Hello @Jacob, welcome to our community!
Is your AirGradient a fully-assembled or a DIY-kit version? If it is a fully-assembled version, we recommend using factory calibration. For a DIY-kit, you might want to open up the enclosure to see the PM module’s serial number, and apply a batch-specific algorithm to enhance the accuracy.

If you need our assistance to look into your dashboard, please feel free to contact us and refer to this thread. Please provide your AirGradient serial number.
