SCD30: Calibration of CO2 and Temperature

Products & Technology Grove
#1

Hello, I have a Seeed Studio SCD30 Grove-Sensor.

  1. it outputs the temperature 4 degrees too high. How can I setup an offset to get correct values?

  2. To auto-calibrate the CO2-value you have to run it for 7 days with minimum 1 hour a day in fresh air. Can I calibrate it manually (set an offset) by using a reference-Co2-measure-device?

Thanks for help!
