Publication number: 20200355665Abstract: A technique for monitoring and collecting environmental data is provided that supports acquisition and analysis of quality measurements of pollutants by sensors based on different technologies in an integrated manner. The system includes a primary substrate having a plurality of sensor modules, each sensor module configured to couple to a sensor, and a manifold having a plurality of flow hoods, each flow hood disposed on a top surface of a sensor and connected to another flow hood or component in the manifold. In some cases, the sensor modules are gas sensor modules, and the sensor is a gas sensor. The manifold thus provides a closed system through which a fluid sample can flow across a series of gas sensors in an actively controlled manner that enables independent flow control over each individual gas sensor while limiting exposure of the fluid sample to potential sources of contamination.Type: ApplicationFiled: May 10, 2019Publication date: November 12, 2020Inventors: Salvatore Mazzola, Bassam Samih Dgheim, Davida Herzl, Meghan Elizabeth Thurlow
