Summary of ENS160 IS A DIGITAL MULTI-GAS SENSOR SPECIFICALLY DESIGNED FOR INDOOR AIR QUALITY MONITORING

ENS160 is a compact digital multi-gas sensor for indoor air quality monitoring, using ScioSense TrueVOC™ technology with four independent MOX elements and on-chip algorithms to report CO2-equivalents, TVOC, and AQIs. It offers SPI or I2C interfaces, separate VDDIO, integrated sensor fusion, automatic baseline correction, heater control, and high immunity to siloxanes and humidity. The device supports wide temperature and humidity ranges, provides raw sensor data, has fast warm-up, low BOM needs, and comes in a 3.0 x 3.0 x 0.9 mm LGA package suitable for reflow soldering and tape & reel.

Parts used in the ENS160:

ENS160 digital multi-gas sensor (LGA packaged device)
MOX sensor elements (up to 4 independent elements integrated in ENS160)
On-chip algorithms and sensor fusion (integrated in ENS160)
SPI or I2C slave interface (integrated in ENS160)
Separate VDDIO supply pin (external power rail 1.71 to 3.6 V)
Heater drive control (integrated in ENS160)
Interrupt engine (configurable, integrated in ENS160)
PCB footprint for 3.0 x 3.0 x 0.9 mm LGA package
Reflow soldering and tape & reel handling (assembly/process requirements)

ENS160 is a digital multi-gas sensor specifically designed for indoor air quality monitoring, offering optimum detection of a wide range of gases and volatile organic compounds (VOCs), including toluene, hydrogen, ethanol, NO₂, and ozone.

Based on ScioSense innovative TrueVOC™ technology, ENS160 combines the flexibility of four independently controlled sensor elements, based on metal oxide (MOX) technology, with intelligent on-chip algorithms to calculate CO₂-equivalents, TVOC, and various air quality indices (AQIs).

The LGA packaged device offers an SPI or I²C slave interface with a separate supply for host communication.
