set-forced-recalibration-factor

Forced recalibration (FRC) is used to compensate for sensor drifts when a reference value of the CO2 concentration of the air surrounding the SCD30 is available. For best results, the sensor has to be run in a stable environment in continuous mode at a measurement rateof 2s for at least two minutes before triggering this node. Setting a reference CO2 concentration using this node will always supersede corrections from set-auto-self-calibration and vice-versa. The reference CO2 concentration has to be within the range 400 to 2000 ppm.
