A portable sensor‐system based on solid‐state gas sensors has been designed and implemented as proof‐of‐concept for environmental air‐monitoring applications, malodours olfactometric control and landfill gas monitoring. Commercial gas sensors and nanotechnology sensors are arranged in a configuration of array for multisensing and multiparameter devices. Wireless sensors at low‐cost are integrated to implement a portable and mobile node, that can be used as early‐detection system in a distributed sensor network. Real‐time and continuous monitoring of hazardous air‐contaminants ( CO, PAH, BTEX, etc.) has been performed in field measurements by comparison of chemical analyzers from environmental protection governmental agency (ARPA‐Puglia). In addition, experimental campaigns of the integrated portable sensor‐system have been realized for assessment of malodours emitted from an urban waste site. The results demonstrate that the sensor‐system has a potential capacity for real‐time measurements of air‐pollutants, malodours from waste site, and control of landfill gas.
