My egg is now online and working!

[Damon Rand]

Hi everyone,

Great news! We just got Bristol's first fully working egg up and
running today thanks to the instructions provided above by Joe/Victor
(plus help from Bristol hackspacers last night).. Very exciting!!

This one is running inside at my house, see the feed here and attached
image. Regarding the image, one the left you see egg data, on the
right you see gas readings in my house over the last ~six hours. As
you can see, when gas heating switches on, humidity drops, temperature
rises and NO2 plummets (perhaps a bit sharply..). Clearly real data
though!!

I will post shortly with a detailed "how to" but basically my last
message to the group was correct.. And of course we have the next egg
build session happening at Watershed on Monday..

PS. If you're inclined to retweet then please do.. :-) twitter: @ceprouk

Best wishes,
Damon.

Hi Damon & others from tuesday's workshop.

I plugged my remote board in and powered it up.

Then added ethernet & finally power to the base station.

before I could get the Arduino serial monitor up they had paired and were talking back to cosm!

No idea what was happening at PM studios but that gives an idea of the time needed for fresh eggs to get together.

Also note that the red 'pwr' led lights up periodically on the sensor  / remote  board, but it doesn't seen to coincide with the various coloured pulsings of red blue green from the baseboard

I see messages like this in my serial monitor with some raw sensor data as 0, which I hope the wicked devices R0 firmware update will fix.

On the down side I can't see the egg on cosm. I just get 'egg not found'. 

Happy measuring

Toby

Ah Ha! Mystery solved.

Egg now registered on cosm. I was cutting and pasting the MAC from the serial monitor and had captured a blank space after the last digit. D'oh!

Any idea if elevation is in feet / yards cm or metres???

cheers

Toby

[Toby]

Updated R0 and it's now running on my desk and outputting numbers :D

See the magic at https://cosm.com/feeds/89740

Maybe elevation is above the street, not sea level.... mmmm

Nice one Toby, those readings looks pretty stable.

I don't know if its any good considering what we heard about the
drop-off of NO2 spikes happening after 20 meters or so but..

There is a government air quality site on Wells road.

I notice that the BCC Wells Road site is reporting a 24 hour high for NO2 of 67 µgm-3 which equates to 33 ppb whilst your egg, and many others for that matter, is reporting values of around 600 ppb. Also, normal CO levels are around 10 to 200 ppb according to http://www.air-quality.org.uk/04.php rather than the 300,000 ppb range being commonly reported. I haven't played with my egg yet so I don't know what can be changed to produce more realistic, but obviously still uncalibrated, values. Any ideas?

There is a recent post on Wicked devices blog about this.
http://blog.wickeddevice.com/?p=388

And take a look at this thread if you want the detailed version
complete with calibration spreadsheets.
https://groups.google.com/forum/#!msg/airqualityegg/tBY_Vwh8LHo/pYDLJ7vNBXkJ

NO2 at least looks like its ballpark, yes CO is way off. Still looks
like its getting better..

Cheers,
Damon.

Actually, I found some good documentation here.
https://docs.google.com/a/cleanenergyprospector.com/document/d/1H1Ul2SzwXkJpdXGmgnuToOhtt7pjg2RVEUEVk0KCiwY/edit

Air quality egg is a bit like an Internet treasure hunt. There are
easter eggs hidden around the web if you know where to look. ;-)
