Hi Sir,
Our customers reported that the temperature and humidity measured by HDC2010 has a large deviation. Comparing the value measured by the calibration instrument with the data directly monitored by HDC2010, it is found that the tolerance is far greater than ±2%.
The measured data is as follows:
The schematic design is as follows:
The register data that HDC2010 reads the temperature and humidity data as follows:
SENSOR_PW_ON _DELAY_MS(100) R 80 04 [00] R 80 0F [00] R 80 0E [00] W 80 07 [00] W 80 0F [01] _DELAY_MS(6) R 80 04 [80] R 80 00 [4E 69 1E A0] R 80 0F [00] R 80 0E [00] temp:27.87C humi:62.54% SENSOR_PW_OFF
Can u help to analyze the cause of this problem?
Thanks,
Best Regards
