Digital Metal Oxide Multi-Gas Sensor - ENS160

Product Specification

Digital Metal-Oxide Multi-Gas Sensor Description：

The ENS160 is a digital multi-gas sensor solution, based on metal oxide (MOX) technology with four MOX sensor elements. Each sensor element has independent hotplate control to detect a wide range of gases e.g. volatile organic compounds (VOCs) including ethanol, toluene, as well as hydrogen and nitrogen dioxide with superior selectivity and accuracy.

For indoor air quality applications, the ENS160 supports intelligent algorithms to digitally process raw sensor measurements on-chip. These algorithms calculate CO2-equivalents, TVOC, various air quality indices (AQIs) and perform humidity and temperature compensation, as well as baseline management all on chip! Moreover, a development option is available to digitally output raw sensor measurements from each sensor element for customization. The LGA packaged device includes an SPI or I²C slave interface with separate VDDIO to communicate with a main host processor. The ENS160 is a proven and maintenance-free technology, designed for high volume and reliability.
