Regarding the BME280 Combined humidity and pressure sensor. I have a question regrading the nist traceable calibration. Is this sensor nist calibrated? If not can it be calibrated with nist and what is the procedure for this? Thank you.
Each BME280 is factory calibrated and trimmed before shipping to the market. However, due to the mechanical stress after PCB assembly BME280 can be calibrated again in users' final products. We have an application note about how to do two-point humidity calibration. Please send a message to us and let us know your email address so that we can email you the app note.
