Smart Cable Air

SCA is a multi-sensor microsystem (MSM) to monitor for the presence of toxic chemicals (TICs), pollutants, volatile organic compounds (VOCs) and flammable gases in air.

The SCA integrates temperature, relative humidity, ionic compounds and metal oxide hotplate sensors. It exploits Temperature and Voltage Cycled operation combined with Electrical Impedance Spectrometer (EIS) to achieve improved gas discrimination. Alternate Current (AC) readout is less sensitive to drifts plus EIS allows to derive the sensor’ R/C equivalent circuit to decouple components that drift from the ones that represent the response to the gas, in support of drift mitigation algorithms. Thanks to its versatile analytical instruments and availability of on-board Interdigitated Electrodes, SCA is also an excellent experimental board for new sensitive materials. Several SCAs can be installed onto long cables for large area continuous monitoring.
