Yeah, that's the Pachube guys project.

Hey all,
Project Safecast (http://www.safecast.org) is now starting to branch out to more environmental metrics. One of these is creating a platform to sense, record, and map air quality data; hopefully in real-time. Interesting in helping us all brainstorm how to do this?
Thanks!

* email is painful so I'm trying to keep messages short and direct. Please excuse my brevity. Here's 6 tips to make email suck less for everyone.
Can you list sources for each of the sensors listed below?

Your goal, for a sub-$300 air quality sensor kit, is very much along the lines of what we're trying to do.
I did do a quick look and found the raw sensors, very inexpensive, $5 and up.
http://www.futurlec.com/Sensors.shtml
There is one sensor for multiple gases
http://www.futurlec.com/Air_Quality_Control_Gas_Sensor.shtml
that needs associated pressure (or temperature) and humidity sensors to be more accuracy. See point later below.
And looking quickly at one profile history, I found this with 70 air sensors:
http://www.mouser.com/Sensors/Air-Quality-Sensors/_/N-55c0b/
most with circuit boards, running $30 and up.
More sensors
http://iteadstudio.com/store/index.php?main_page=index&cPath=4&zenid=v9410sjq32j4u8d4pb46r1vpc1
None of these sites are the one I found with over a hundred sensors.Terrific. I'd like to see it be compatible with RadioShack's weather station Internet interface, to name one. Both hardware and software and API.
What the new group is about is to expand Safecast from just radiation mapping into a general environmental mapping platform.
Fantastic.
My interest in this, besides capturing large scale environmental data, is to get students involved in carrying out research, especially in the citizen science model.
My BS is in Physical Chemistry from Harvey Mudd College, specializing in EMF and charged particles, with minor in EE, Management and Ceramics. I'm now focused on immuno-neurology, nerve transmission, cosmology, and a few others I track. Teaching and lecturing I try to do monthly. I'm told I'm good with children. Adults I find are slow. ;-)
I'm a physics teacher who is building a student research program out at the Wildwood school in west Los Angeles
I'll give it a try. I'm trying to close new contracts, so my time can be unpredictable rushes to prep the deal's paper work.
( http://scienceland.wikispaces.com/PEER ), and I've already had a few students work with Safecast.Could you meet at CRASH Space this coming Tuesday at about 6:)0? I'll be there either way from six to ten.
I like meetings with agenda items, and everyone leaves with some 'homework' they committed to research, implement, write, etc, within a time frame. My days in college and aerospace showing through. :]
Agenda Items
List of sensors needed on base array.
Application set of sensor types listing 2 or more sensors as addon to the base array
Mix and Match methods:
- Common high voltage supply 5 to 10KVDC for those sensors that need HV.
-- Point is multiple high voltage supplies on the base circuit board is expensive
-- List such sensors along with brand and needed HV.
- Time slicing 2 or more sensor types?
-- reducing the overall wattage is desirable for solar or battery run unit
-- Power up only one sensor at a time, wait for readings to stabilize, and move to next one
-- Needed "alarm" levels moving towards dangerous levels
--- Able to power up all sensors option
Sensors needing 'clearing' with fresh air issues
Sensors that get clogged issues
Sensor calibration, troubleshooting, replacement? Kits?
New Items - suggestions during the meeting
Add your agenda items
These are technical implementation issues. There are also human factor ones, that we should list.
Items for discussion this summer:
Los Angeles Grid areas (prevailing downwind of industrial strips, freeways, ocean, airports, tar pits, power plants, oil refineries, ... more...)
Central Processing or decentralized? Crashspace pay for the electricity and bandwidth of a computer?
Backup of data locations?
Analysis power? 3D data visualization? Supercomputer facility (It's free)?
Kit or prebuilt? Both?
Design cost remuneration or not? Rate?
LLC? NFP? Both? Use someone else's?
I'll write up minutes and distribute them. And prepare the next meeting's agenda list.
Peter
Can this be streamed or on a g+ chat?
Although I'm technically in LA right now its just a flight connection back to my island. I miss crashspace.
