ScioSense ENS161 Digital Metal-Oxide Multi-Gas Sensors are based on metal oxide (MOX) technology with four sensor elements supporting isothermal and low-power operating modes. The devices provide an incomparable abundance of fully processed output signals. The independent hotplate control enables the detection of a wide range of volatile organic compounds (VOCs), including ethanol, toluene, hydrogen, and oxidizing gases, with superior sensitivity. The ENS161 offers a low-power mode (700µA average current consumption) and an ultra-low-power mode (150µA average current consumption). This ENS16 supports intelligent algorithms to process raw sensor measurements on-chip. These algorithms calculate TVOC- and CO2-equivalents, various air quality indices (AQIs), perform humidity and temperature compensation, and baseline management, all on-chip.
The raw sensor measurements can be read for further customization. The ScioSense ENS161 is offered in a compact 3mm x 3mm x 0.9mm LGA package with SPI and I2C slave interfaces to communicate with a primary host processor. The ENS161 is an established and maintenance-free technology designed for high volume and reliability.
