[Stoves] PM measurement with Speck

[Christina Espinosa]

I asked Kirk Smith if he had used this one before and here is his response
regarding these type of PM devices for the home from tests they have run:

"There a number of PM devices on the market now designed for general
consumers -- at least a dozen in China alone. plus some here.  We have
evaluated several and are doing another batch here soon at our lab in
Richmond.  So far, none has the combination we want of

-- precise and stable enough readings
--small and light enough for personal monitoring
--ease in zeroing and calibrating
--high enough upper limit -- they typically stop at 1 mg/me or lower
--ease in cleaning -- necessary for our environments or even in dirty Asian
cities
--reasonable battery life
--easy datalogging, downloading, etc

Our UCB-PATs+ does meet these criteria and is now undergoing field
trials.   (We are also flying it on our aerial particle monitor (drone) in
India.)  Would not expect it to be commercially available (from BA) until
early next year, however."
