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
  • Pictures: later...
