The ENS161 has a 'standard' hot-plate MOX sensor divided into 4 sections, as well as a small microcontroller that controls power to the plate, reads the analog voltage, and provides an I2C interface to read from. ScioSense provides an Arduino library with examples of reading the four raw resistance values and also the TVOC and eCO2, and a Python/CircuitPython library that can be used with Linux computers like the Raspberry Pi or our CircuitPython boards.
