Arduino Shield for AirCasting. Simpler than their wiring mess.

Revision 1

Hardware

  • 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

Software

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.

Revision 2

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]
