We actually plan to bring the version back that needs soldering. We took it temporarily out of the shop because a number of people overestimated their soldering skills and couldn't get it running. The usb and jst plug are difficult to

Author here. I'm planning to do some more comparison testing of PM modules and planning to benchmark modules from Sensirion, Plantower, Cubic and AlphaSense. Let me know if you know some other sensor modules that could be interesting.

The range is up to six thousand dollars, not six dollars.

One more thing that could be of interest. We are currently running a very large global co-location project where we place our open hardware monitor next to reference devices. The aim is to develop algorithms to compensate for different envi

Yes I agree on this one. I reposted it because I thought this could be quite interesting for the hn crowd. On the 4th time it got more than 200 comments. Since then I did not repost it again.
