sensor box and particle detection

Posted by on Apr 14, 2021 in Design, Environmental | No Comments

Installed a couple of particle detectors that count particle sizes of 1.0, 2.5, and 10.0 microns.  Looking at these values along side CO2 and tVOC in the kitchen is one functional test.  Last night I used Alton Brown’s “Election Night Steak” recipe, and on the printed copy I’ve written “only cook in summer” because of all the smoke.  So last night it was in the low 60s, I figured I could just open a window and run the exhaust fan and it would be fine.  Nope.  Two minutes in to cooking and the smoke detector in the hallway next to the kitchen went off.

What surprised me the most is how high the PM levels went in my office, up a flight of stairs, with the furnace off (because the window was opened).  As I heated the cast iron pan for five minutes, the CO2 and tVOC levels went up in my office.  I think if you look at the PM spike you can see where the steak started filling up not just the kitchen, but the house, with smoke
