This board is easy to be connected to any microcontroller as it uses I2C. There is a seperate HDC1080 temperature and humidity sensor on the board that should be read and fed back into the CCS811 for better calibration. The temperature reading of the CCS811 is not good and should be ignored as stated in the library documentation. I use the standard library for Arduino to read both sensors. The pin WAK (wake) should be defined by either a microcontroller pin or linked to GND. The board needs 48 hours of operation to burn-in. After that, the boarfd is stable. I got two boards and the results are very reproducable. If the board is not well grounded, static electricity may build up and lead to high readings over time. A reset will clear that. Very good value for the money
