AMS Digital Metal Oxide Multi-Gas Sensor - ENS160

AMS Digital Metal Oxide Multi-Gas Sensor ENS160 Description:

ENS160 is a digital metal oxide multi-gas sensor solution based on metal oxide (MOX) technology and 4 MOX sensor elements. Each sensor element has independent hotplate control to detect multiple gases, including volatile organic compounds (VOCs) such as ethanol, toluene, hydrogen, and nitrogen dioxide, with excellent selectivity and accuracy. For indoor air quality applications, ENS160 supports smart algorithms to digitally process raw sensor measurements on-chip. These algorithms calculate CO2 equivalents, TVOC, and different air quality indices (AQIs), and perform humidity and temperature compensation as well as baseline management – all on-chip! Additionally, development options are available for digital output of raw sensor measurements for each sensor element for customization. The LGA package device includes an SPI or I2C slave interface with independent VDDIO for direct communication with the main processor. ENS160 is a mature, maintenance-free technology designed for high volume and high reliability.
