• sniff sniff … do you smell that? • No need to stick your nose into a carton of milk anymore, you can build a digital nose with the Adafruit SGP41 Multi-Pixel Gas Sensor , a fully integrated MOX gas sensor. • This is a very fine air quality sensor from the sensor experts at Sensirion, with I2C interfacing so you don’t have to manage the heater and analog reading of a MOX sensor. • It combines multiple metal-oxide sensing and heating elements on one chip to provide more detailed air quality signals - and, unlike the SGP40, the SGP41 adds a dedicated NOx sensing pixel so you can measure both volatile organic compounds (VOC) and nitrogen oxides! • The Adafruit SGP41 Multi-Pixel Gas Sensor Breakout guide has everything you need to get started with this sensor. • There’s pages for overview, pinouts, CircuitPython, Arduino and resources for download.
