I got PM 2.5 sensor from Xiaomi for $24.99. I am not sure if it works correctly. It shows 002-003 all the time. https://a.aliexpress.com/_Eu7cPbR https://a.ali

Yet you spam an affiliate link. Mods, please take a look at this user's comment history, it seems like spam is their main purpose...

  If you look up a product in the AliExpress app and copy the link, this is what you get. It does not give you any commission unfortunately. So it's not an affiliate link.

    That's correct. I posted a link from a product I just bought and received.

That's pretty normal in a home. The sensor of my Xiaomi air purifier always shows similar levels. But one time there was a slight smell of burning outside (a little bin fire 100m away) and it immediately went to 200+ despite there not being visible smoke. Also, my await lite tracks the graph of the Xiaomi pretty well. I guess most fine dust comes from outside. Unless you're frying or 3D printing which elevates levels here in my house for sure.

  Sorry that should be "Awair Lite"
