Micropython module for work with ENS160. ENS160 is a digital multi-gas sensor specifically designed for indoor air quality monitoring, offering optimum detection of a wide range of volatile organic compounds (VOCs) and oxidizing gases.

Upload micropython firmware to the NANO(ESP, etc) board, and then *.py files: main.py, ens160sciosense.py, and sensor_pack folder. Then open main.py in your IDE and run it.
