The spatial distribution and variation of gases is heavily utilized in environmental modeling and pollution monitoring. Key requirements are low-power sensor nodes capable of unmanned operation over extended intervals, and the capability of wireless communication to a base station for real-time data aquisition. Examples of sensors under developement include a fiber-based CLaDS scheme for passive methane detection, and highly-accurate CO2 sensor nodes employing real-time calibration via spectral correlation. 

Projects:

• Distributed, fiber-coupled sensing using CLaDS
• Wireless Sensor Network for CO2 detection
• High-accuracy sensor node
