Someone did a Amazon review on it and said
"This PM2.5 was extremely easy to add to my WS2000. We have a local DEQ/EPA air quality station in Bend, and my PM2.5 data is consistent with what the DEQ station is measuring. The best part about this excellent WS2000 weather station is the super cool customer service offered by Ambient Weather. Ed and their staff are very quick to address the questions I might have. The USFS and BLM periodically have controlled fires to burn forest debris and the PM2.5 alarms when the smoke is harmful for outdoor activities. Check out the attached screen captures."
This included images of the PM 2.5 data on the Ambient site.
https://www.amazon.com/gp/customer-reviews/R28EA4W9XX8XEI/ref=cm_cr_arp_d_rvw_ttl?ie=UTF8&ASIN=B07XSFCYLWI wonder which sensors that Wundermap is getting the PM 2.5 data from. As there is a PM 2.5 and a PM 10 filter, which brings back a few data points showing up. It would defiantly make sense for Wundermap to allowed the Ambient PM 2.5 sensor to submit data to it, especially if the data already shows up on Ambient's site (It should show up on Ambient, other wise I can't see why one would buy/add the PM 2.5 sensor if you got no stored/online data from it). I wonder if they'll allow back logs of the data, if they decided to allow it to go though on Wundermap. And I wonder how many people own Ambient PM 2.5 sensors. I never realized that Ambient PM 2.5 (and probably PM 10) don't show on Wundermap. I'm not sure as to what date or month the PM 2.5 sensor was released.
