PMS6003 sensor consideration

Components
#1

Hello. There’s a newer Plantower sensor PMS6003 that seems to use dual lasers to double its lifespan. The newer PurpleAir products use it. Based on this research paper:

  • PMS6003 detected particles larger than 2.5 μm in diameter whereas PMS5003 did not.
  • PMS6003 needs new correction factors.

Have you looked into this newer sensor?

According to the spec sheet, the mean time between failure goes up from >3 years to >10 years, but the spec sheet also shows both should detect the same particles, although the research paper you linked shows otherwise.

The ESPHome firmware appears to support all of the PMSx003 line, so could be a drop in replacement, other than the correction algorithms

Not sure if the physical dimensions are the same.
