Can ADPD188BI distinguish between Smoke and Dust ?

Hi All,

This is SK Lee of Analog World in Korea. (I'm in charge of DFAE.)

I have a question for ADPD188BI.

(background and question)

In Korea market, false alarm occurs on days with a lot of fine dust.

So it is necessary to distinguish between smoke and dust in Korea Market.

Is it possible to distinguish using PTR and Ratio ? (with Blue and IR)

    Can you email me at my Analog email address for a more detailed discussion?

    What do you mean by fine dust? Is it gradual dust buildup on the smoke detector that causes false alarms or dust floating in the air?

    There are possible techniques that can be investigated for both scenarios. We need some more context to investigate this further. Currently we are working on a solution that manages dust in some use cases, will require more detailed discussion.
