   PCB of the day! SGP40 Air Quality Sensor Breakout - VOC Index - STEMMA QT / Qwiic 👃🥛🌬️

   *sniff* *sniff* ... do you smell that? You no longer need to stick your nose into a carton of milk; you can build a digital nose with the SGP40 Multi-Pixel Gas Sensor, a fully integrated MOX gas sensor. This is an excellent 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.

     @adafruit could this be used as a fart detector? Asking for a friend.
