Product Overview

The ENS160 Air Quality Sensor Module measures equivalent CO₂ (eCO₂), total volatile organic compounds (TVOC) and an indoor air-quality index, over a simple I²C connection.

Its on-chip processing delivers ready-to-use readings — no analogue calibration — for smart-home monitors, HVAC control and IoT dashboards.
