AirCasting Shield Release status: obsolete [box doku]

Description	Arduino shield for AirCasting

Deprecated: See Environmental Monitor which is the follow up project

Arduino Shield for AirCasting. Simpler than their wiring mess.

Sensors: SHT22, MQ-7, MQ-135
- Proper heater drive for MQ-7, thanks to Citizen Sensor [1]
Board: Prototype milled at OHM2013

Issues:
- MQ-* sensors didn't fit into their holes -> holes to small. Also pads to small, soldering was a pain and required some hacking to the board.
- Relais fairly loud.
- Sensors get quite warm

Arduino firmware, using some DHT22 Tutorial and this MQ-7 Library (with a few changes to fix stuff) for proper heater driving.

DHT22 returns legit data
MQ135 could be legit
MQ7 is oddly low.
Both gas sensors can't report real ppm values, as they would have to be calibrated.
Bluetooth works fine.

Phase: Planning

Can keep DHT22 sensors
Should switch so electrochemical sensors for gases.
- Nemoto NAP-505 [2]
- Figaro TGS5342 [3]
- e2v EC4-500-CO [4]
