[UPDATED 03-02-2018] SMOG sensor – 2,5 and 10 micro meter particles

[Last changes]:
07-11-2017: Additional data from richer stations, Open-Smog Integration
20-12-2017: USB power control on Raspberry Pi 3, thanks to reader
02-03-2018: New API from GIOŚ Poland

SMOG is common nowadays in big cities. Let’s put together a working, precise own SMOG sensor, first for the 2,5 and 10 μm size particles. There is one issue – the choices are many, but only few are reliable, precise and have affordable price. Finally – after a log searching, I’ve chosen Nova Fitness SDS011:

  • precision is OK
  • fan included
  • ability to mount a small tube to access external air
  • very realiable
  • UART with USB converter included
  • Low Total cost: around $40 (with Orange Pi Zero) up to $60 (with Raspberry Pi)
