The detection of flammable gases is necessary to avoid explosive atmospheres. For this reason, low-cost pellistors are frequently used sensors, although they suffer from high operation temperatures and high power consumption. Within the scope of our work, we present a novel wireless low-power catalytic gas sensor system for flammable gases. The combination of a MEMS-based sensor and low power radio system provide the opportunity to monitor complex infrastructures without using the grid for power supply.
