In need of particle counter sensor (full working)

Hi for a prospect i am searching for a particle counting sensor based on LoRa. For a project test to build in a machine within 7 days from now. Can anybody help and make an offer.

did you search for commercial solutions ?
what type of particles (10 / 2.5 ? smaller ?)

  • 27 days ago you mentioned you build one ?

there is some info on this board… but mostly about DIY building and with parts from China you won’t make that in a week

No commercial outdoor available. 27 days ago i didn’t mention PM meassurements as you can read.

I have a few. In Alkmaar NL
