Sensor Systems for Detecting Gas Plumes-Robots and Sensor Network

Abstract

Two kinds of sensor systems for detecting gas trail (so-called plume) are discussed. One is the mobile robot with several kinds of sensors which can track the gas plume to search for a gas source. The other is the sensor network which can reveal the spatial and temporal behaviors of air-pollutant plumes in detail. The sensor network can also perform an automatic calibration to achieve a maintenance-free operation.
