The product is one of the first from startup ScioSense BV (Eindhoven, The Netherlands), a spin-off company from AMS (Unterpremstaetten, Austria).
The embedded intelligence enables the CO2 equivalent output to take account of human-generated gases and provides for an adaptive baseline configuration.
The micro-hotplates provide lasting immunity to contamination by siloxanes, and the part is suitable for use in indoor residential, commercial, professional and in-cabin automotive settings.
The multi-element technology is sensitive to oxidizing gases such as ozone which affect the quality of indoor air, as well as to volatile organic compounds (VOCs) such as toluene, ethanol, methane, sulfur dioxide and carbon monoxide. The algorithms supplied with the ENS160 produce three measurement outputs:
Total VOCs (TVOC), which draws on the broad sensitivity of the ENS160 to human-generated and artificial VOCs
eCO2, a commonly used proxy measurement for the density of human occupation of an indoor space
Various air quality indexes which are compatible with international standards
The ENS160 also provides its raw gas measurements for OEMs which want to apply proprietary algorithms.
The ENS160 has a reduced a start-up time on first use and warm-up time after each power on of less than 5 minutes.
The sensor is housed in a surface-mount package which measures 3mm by 3mm by 0.9mm and provides outputs via a serial peripheral or I2C interface. Since all the sensor’s measurement algorithms run on the ASIC on an embedded Cortex-M0 processor core.
