Arduino Shield for AirCasting. Simpler than their wiring mess.
Hardware
Revision 1
- Sensors: SHT22, MQ-7, MQ-135
- Proper heater drive for MQ-7, thanks to Citizen Sensor [1]
- Board: Prototype milled at OHM2013
- All sensors return data that seems legit at first sight.
- 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
