How can we improve sensor accuracy for community air quality projects in areas with high humidity?

[pjg]

How does the community use the PM2.5 data that is recorded at humidities above 70%?

Unfortunately, the AQMD site is down. If even the US .gov websites do not work when I need them… The sensor in this system is probably a chinese stuff as well and probably not RH corrected. The accuracy issue with RH is mostly a merchant of doubt technique… SC produce the raw data. We could/should implement an humidity correction on the map but it will start long debates about which one etc. The RIVM in Holland is developing a correction algorithm which spreads among the low cost sensors bu…

Can you tell me a bit more about the inconsistencies ?
The Next PM from TERA contains an heater. It can be precisely control and monitored in the last firware according to TERA’s Marketing department.
