About this item

The Adafruit ENS160 MOX Gas Sensor is a compact, I²C-based sensor designed to detect indoor air quality by measuring total volatile organic compounds (TVOCs) and equivalent CO₂ (eCO₂) levels. It features a built-in microcontroller that manages the sensor's heating elements and provides digital outputs, eliminating the need for complex analog readings. The sensor operates over a voltage range of 3.3V to 5V and includes temperature and humidity compensation to enhance accuracy. Its small form factor and STEMMA QT/Qwiic compatibility make it ideal for integration into various microcontroller projects, including those using Arduino and Raspberry Pi platforms. The ENS160 is suitable for applications such as air quality monitoring, HVAC systems, and environmental sensing.
