New rules on moisture content come into effect today

 The old fella took out a garden hose and started sprinkling the wood with water, said it made it last longer............... 

 

As long as the person that gave him with the wood can't be prosecuted for suppling it with a high moisture content then that's fine 🤣 😂

How do I prove it?!

Thanks to @Dan Maynard I was able to save a logfile and produce a chart for about 11 hours today, some 8000 records.
Below is the result from outside the front window of this room 1.2m from the ground, 6m from a holly hedge and a further 6m to a minor through road. The results are for pm2.5 in microgram per m3 of air.
 
I did not operate any machines (deference to Sunday) but did light the stove at 20:15 just to see the result as it was fairly warm this evening.
 
From the timing of the other spikes I suspect local barbecues but I was out most of the afternoon.
 

This is really interesting, I've been mulling the idea of averaging to smooth out noise but the spikes from BBQ are quite brief.

Also, presumably the spike from your stove is just the smoke on starting? There's another small one about 15 mins later which might be you put ting some logs on?

It would be good to do this across a week to compare weekend BBQ, and across the year to see wood stove Vs summer. Also correlation with wind speed.

If I had less to do I'd be buying one of these meters....
