We present an environmental monitoring system based on wireless sensor network for air quality measurement and natural gas leakages. The system is based on catalytic off-the-self available gas sensors and on a novel strategy of sampling and processing which permits to reduce the energy consumption of one order of magnitude. The characteristic of the sensing device has been extracted both with the standard utilization and the new proposed approach, to compare and validate our results. Moreover the importance of the humidity present in the environment has been taken into account and included in the model, because it severely affects the measurements. The wireless sensor network developed has been also extended using a smartphone to enable data sharing over internet and to enhance portability of the overall system.
