Adafruit ENS160 MOX Gas Sensor - Sciosense CCS811 Upgrade

*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 ENS160 Gas Sensor, a fully integrated MOX gas sensor. This is a very fine air quality sensor from the sensor experts at ScioSense, 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.
