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 . 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 gas sensors Integrated sensor measurement and heater drive control Integrated pre calibrated sensor fusion and automatic correction algorithm Multiple IAQ outputs (TVOC, ec02, AQL) 12C and SPI interface Less than 1 minute warm-up Less than 1 hour 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 Ambient - 40 to + 85 ° C / 5 to 95% RH VDD1. 71 to 1.98v Color: As Shown Material: PCB Package Contents: 1 * ENS160 module Only the above package content, other products are not included.
