HDC2010: Response of the board distance

Part Number: HDC2010

Hi, Team,

When checking the response of the sensor on the board, it was confirmed that the response was very slow when moved closer to or away from the heat source as shown below. (It takes about 120 seconds for the value to converge)
* The reading frequency of the measured value is set to 1Hz (1sample / sec).
Address 0x0E Configuration Register AMM [2: 0] = 101

Could you tell me if there are any register setting items related to responsiveness? (For example, averaging processing, number of taps of IIR filter, etc.)

In the data sheet, we found a description that the responsiveness may change depending on the heat capacity of the land pattern around the sensor. Is there a possibility that the surrounding land pattern will lead to the above level of responsiveness deterioration?

Best Regards,
Satoshi Yone

  • Dear Yone-san, 

    It appears to be very subjective and perhaps uncontrolled test - this device is arranged to get heat transfer from the ball/pin connections to the part. Generally this is the package type with the fastest thermal response because there is no mold compound to heat up. 

    can you describe the test a bit more or provide pictures to help us understand the conditions better?
