HomeMatic Gas Detector

Today I built a HomeMatic gas detector. Now when gas is detected, our HomeMatic smoke detectors are enabled.

Here is a list of the components I used:

  • Gas sensor Schabus GX-SE
  • HM-SCI-3-FM
  • DC/DC converter (5V/3,3V) Aimtec AM1S-0503 (to power the HM-SCI-3-FM)
  • 5V Relais FiC FRS1B-S-DC05 (for volt-free switching of the HM-SCI-3-FM)
  • USB type B socket for power
