    Some other review didn't do this justice. This is 2 I2C devices, they share the same SDA and SCL pins on the pinout as what I think is master and slave config.

    Scanning...

    I2C device found at address 0x38

    I2C device found at address 0x53

    done

    I just have VIN, GND, SCL and SDA attached to the microcontroller.

    I can't find the support files for this. There was no documentation, I could only get the temperature working.

    The ens160 has great potential as environment sensor, tried this board using esphome, esp8266 and github://pr#4243 as source software. Worked great for 24 hours, it detected meals servings in the house and open alcohol three feet away with strong signal, but then after 24 hours both voc and Co2 sensors started showing zero values and loss of sensitivity, then another day all zero output even with strong voc exposure.
