Indoor ENS160 Air Quality Sensor - I2C

The ENS160 Air Quality Sensor uses ScioSense's ENS160 chip with TrueVOC and metal oxide (MOX) technology to monitor indoor air quality. It outputs TVOC (total volatile organic compounds), eCO2 (equivalent CO2), and AQI (air quality index) readings via I2C, with intelligent on-chip algorithms that provide ready-to-use environmental data.

The probe-style form factor makes installation straightforward, and the built-in automatic baseline correction algorithm ensures long-term measurement stability. A warm-up period of less than 3 minutes is recommended for accurate readings.
