dear sir
i test 3100 rtc function with SDK release_mra2_10_1_nhs3100,i use the app_demo_dp_tlogger project with the APP NHS3100 temperature logger.
i know the procedure when use the 3100 about rtc
is there anything wrong ?why 3100 rtc is not accurate as expect ?
Hi,
The TFRO is calibrated during production at 30ºC but only for a short time, limiting costs and accuracy. With a fixed environment and steady battery voltage, the deviation will be constant - we didn't find any significant aging effect. There is more information available in the SDK release zip file you downloaded under <SDK>/docs/AN_NHS31xx_RTC_accuracy.pdf.
Kind regards,
Dries.
