Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Can't enable auto-calibration of SCD41
I want to enable the auto calibration (ASC) mode for the SCD41 but it doesn't seem to work. I connected the SCD41 to an ESP8266 and used an Arduino IDE and the Sensirion Arduino library https://github.com/Sensirion/arduino-i2c-scd4x. The code I used to enable it is scd4x.setAutomaticSelfCalibration(1) and it outputted 0, which indicates that it is enabled successfully. But when I checked the status of ASC with getAutomaticSelfCalibration(), it outputted 0, which indicates that the ASC is disabled and getAutomaticSelfCalibrationInitialPeriod always outputs16383, which indicates that there are still 16383 hours until the first ASC.

Very basic I2C help
Depending on what you want to do, there's also a SCD4x library straight from Sensirion that you can use with Arduino. I've used it successfully with the SCD41. Sensirion's examples usually start with reading the serial numbers of their sensors, although with the help of library functions.
