7Semi ENS160 Air Quality Sensor I2C Probe

The 7Semi ENS160 Air Quality Sensor I2C Probe is a compact, ready-to-use air-quality sensing module based on the ENS160 metal-oxide (MOX) multi-gas sensor. It measures volatile organic compounds (VOCs), oxidizing gases, and other indoor pollutants, and provides processed digital outputs including equivalent CO₂ (eCO₂), total VOCs (TVOC), and Air Quality Index (AQI). With its I²C interface and stable performance across wide environmental conditions, this probe is ideal for smart-home devices, HVAC systems, air purifiers, and IoT-based indoor air-quality monitoring applications.
