ENS16x Digital Metal-Oxide Multi-Gas Sensor Family

ENS16x Digital Metal-Oxide Multi-Gas Sensor Family.

Versatile Digital Air Quality Sensors for Building Automation, Appliances & Consumer Applications.

ENS16x is a range of digital multi-gas metal oxide (MOX) sensors, specifically designed for indoor air quality monitoring, offering an unrivalled wealth of fully-processed outputs including low-power operating modes.

With its innovative TrueVOC® technology, the ENS16x combines detection of a wide range of gases including volatile organic compounds (VOCs) and oxidizing gases with intelligent on-chip algorithms.

It calculates a series of fully processed outputs such as CO2-equivalents, TVOC-equivalents, a 5-step Air Quality Index (AQI) according to the UBA (German Environment Agency) and a 500-step relative AQI according to ScioSense. Moreover, the ENS16x offers full humidity compensation plus low-power operating modes for power-constrained designs.
