## Description

Build a digital nose for indoor air quality projects with this SGP41 gas sensor breakout. The Sensirion SGP41 is a fully integrated MOX gas sensor with I2C interfacing, so you do not need to manage heater control or analogue readings yourself.The sensor combines two MOX hot-plate sensing elements on one chip: one for VOCs and one dedicated NOx sensing pixel. It can detect a wide range of volatile organic compounds as well as oxidising gases such as nitrogen oxides, making it useful for indoor air quality monitoring and trend comparison.Rather than outputting TVOC or eCO2 values, the SGP41 provides raw VOC and NOx signals that are processed with Sensirion’s Gas Index Algorithm to produce VOC and NOx Index values from 1 to 500, where 100 indicates a typical indoor environment. Like all VOC and gas sensors, it has variability, so calibration against known sources is recommended for precise measurements.Adafruit has mounted the surface-mount sensor on a STEMMA QT form factor breakout with I2C connectors on both sides, standard header pin breakouts, a 3.3V regulator and level shifting for use with 3.3V or 5V systems. Arduino library support is available for reading raw VOC and NOx signals, and a Python/CircuitPython library is available for Linux computers such as Raspberry Pi and CircuitPython boards. A QT cable is not included.

**Product Type:** Gas Sensor Breakout
