New sensors for air particulate sensing

While ordering more Shinyei PPD42NS particle sensors off of aliexpress, I noticed a bunch of other particle sensors that I hadn’t seen before. It would appear measuring air quality is becoming more popular! I even found a full-on portable air quality monitor, but it appears it’s not wifi-connected, and apparantly has no documentation (common for Chinese goods). It’s by a company called Plantower out of China.


There’s also this, which I think is by Plantower too, the SDS011, the SM-PWM-01 (which is another ripoff of the Shinyei PPD42NS), the INSAN CP-15-A3 all in Chinese, and the PMS3003.

Of course there’s the Shinyei PPD42NS and it’s first ripoff, the Samyoung DSM501A, which have been out for a while.
