Digital multi-gas sensor from ScioSense

ScioSense's ENS160 is a digital multi-gas sensor solution based on metal oxide (MOX) technology that is proven and maintenance-free and designed for high capacity and reliability.

The ENS160 supports intelligent algorithms to process raw sensor measurements on the chip. These algorithms calculate CO2 equivalent (eCO2), total volatile organic compounds (TVOC), and Air Quality Index (AQI), and perform humidity and temperature compensation as well as baseline management, all on-chip. Four sensor elements and integrated independent hot-plate control allow for the detection of a wide range of VOC's, including ethanol, toluene, hydrogen and oxidizing gases, with superior sensitivity.

The output value can be read from the controller or processor through the SPI or I²C interface without additional libraries. Combined with the size-optimized 3 mm x 3 mm LGA package, these features make the ENS160 perfect for air quality sensing applications.
