PM 2.5 module - manual?

  • Hi all,

    just received a PM 2.5 module. Is there any place I can check for a manual? after powered on the display is showing 3 areas:

    "standard" and "ambient" show PM1.0, PM2.5 and PM10.
    both "standard" and "ambient" show the same numerica values on the above fields

    then I have the number or paticles, temperature and humididy.

    none of the 3 buttons of the M5 module work, is this intended?

  • @bit2020 this is the normal demo code
