Hi Team,
We have received a report from our customer that the HDC2022 temperature reading had suddenly dropped significantly with respect to a reference temperature. According to the customer,
We have been using HDC2022 in our products and the product was working with expected temperature results since the assembly and all of a sudden the temperature had fallen down by 8 deg C with respect to reference .We have done various test cases to check this, when we have altered the environment temperature , the sensor is responding but again fallen down by 8-10 deg with respect to reference. For ex: The device was reporting 23 deg C where reference was 23.2 for more than 6 months and all of a sudden temperature of a sensor fallen down to 15 deg C where the ref being same.Have done multiple tests ,but sensor didn't work.
What could be the reason for this sudden failure of sensor which was accurate since the assembly. Its urgent ,so please help us to find out the root cause.
Here is the schematic diagram and PCB layout.
Regards,
Danilo
