Dean or Christina or anyone,<br>
<br>
Are the PM sensors just sounding an alarm (like simple smoke
detectors) or are they giving any readouts of actual numbers? Even
if not calibrated to exact standards, seeing the numbers can be of
great help. There are CO detectors that are alarm only and some
that give readouts.<br>

<div>We have three PM sensors here at the lab (under $100) from
China and are interested in quantifying their performance. The
Test Kitchen is set up and we can try some experiments at
Stove Camp for those interested.</div>

WONDERFUL!!! Now this Listserv is really working
together!! So summary of comments and thoughts thus far:<br>
<br>
1. MOST of us were almost unaware of the existence of
Speck, and we find out (thanks Christina) that there are
many such types of units.<br>
<br>
2. But being inexpensive, they have issues of quality of
the data. Evidently not of sufficient quality for the
HEALTH STUDIES requirements of Kirk Smith and his crew.<br>
<br>
3. But for those of us in the "trenches" trying to
understand how to improve the stoves, these small
detectors of PM could be of great assistance. If only to
be able to detect whether the emissions are improving or
worsening would be useful for a stove designer to make
comparisons between one stove with two different
variations.<br>
<br>
4. These smaller PM measurement devices have not yet
entered into the activities of Aprovecho (as developer of
high precision instruments) and therefore have not been
part of Aprovecho activities for Stove Camps where the
inexpensive instruments might be of great interest. <br>
<br>
5. Will these PM sensors be part of Stove Camps? Or
when? I do not have any such sensors, and I am not
intending to attend the Aprovecho Stove Camp in July (27
to 31, I believe). Dean and crew or some attendee might
arrange to have the PM sensors by then.<br>
<br>
But there is another Stove Camp early next month (9 - 10
July) in Ontario, Canada, headed by Crispin PP and Julien
Winter and hosting assistance by Alex English. The focus
will be on the RELATIVELY LOW COST emissions testing
equipment (and procedures) that Crispin knows so well. If
you are not familiar with such equipment or want further
information and hands-on experience, consider attending.
Information about this Stove Camp about Testing is
available from Julien, who I ask to re-post to the Stoves
Listserv the contact information and details / agenda
(with a new Subject line). So, perhaps further
discussion about the inexpensive PM measurement devices
will be included at that event.<br>

<br>
<span style="color:rgb(0,0,255)">"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 <br>
<br>
-- precise and stable enough readings<br>
--small and light enough for personal monitoring<br>
--ease in zeroing and calibrating<br>
--high enough upper limit -- they typically stop at
1 mg/me or lower<br>
--ease in cleaning -- necessary for our environments
or even in dirty Asian cities<br>
--reasonable battery life<br>
--easy datalogging, downloading, etc<br>
<br>
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."</span><br>

<div>I have now two Arduinos, and i will make
(some day) my own datalogger (temp, PM, CO,
oxygen, etc.). The sensors for Arduino's are
not to expensive, and in Internet exists a
lot of examples of this type of devices.</div>

<div>This is, for example, a dalalogger made
