Description:

Ens160 is a digital multi gas sensor specially designed for indoor air quality monitoring. It can best detect a variety of gases and volatile organic compounds (VOCs), including toluene, hydrogen, ethanol, NO2 and ozone. The air quality sensor is used for home and building automation, consumer goods, electrical appliances and air purification

Detection of reducing (VOC) and oxidizing gases (such as NO2)

MOX supports up to 4 independent gas sensors

Integrated sensor measurement and heater drive control

Integrated pre calibrated sensor fusion and automatic baseline correction algorithm

Multiple IAQ outputs (TVOC, ec02, AQL)

I2C and SPI interface

< 1 minute warm-up

< 1 hour start

High resistance to siloxane and humidity

Ease of use. Selection of multi standard air quality signal

Easy integration. No software library is required, which has no impact on the host CPU

Ideal for fast response systems

Safe use of daily necessities

Suitable for flexible and robust design
