LPS25HB数据读取出现6.4mBar偏移误差

嗨，
 
 LPS331AP和LPS25HB传感器具有类似的寄存器映射，但它们不相同。
 我建议检查初始设置。您可以找到两个设备的数据表。
 您是否在自定义电路板上焊接了设备？
 如果设备报告的偏移值小于预期值，则可能需要单点校准以补偿焊后封装应力。

Hi,

the LPS331AP and LPS25HB sensors have a similar register map, but they are not same.
I suggest  to check the initial setting. You can find attached the datasheet for both devices.
Do you have soldered the device on your customized board?
If the device is reporting a value with a small offset compared to the expected one, a single point calibration may be needed in order to compensate the post soldering package stress.Regards

​Hi,


I working with Barometric Pressure sensor LPS331AP.Its working good. but as this chip absoluted,then we changed design to LPS25HB.But this chip is reading 6.4mBar error apart from the actual measured value .We are not added any offset value and not done any our factory calibration.Just I reading the 24-bit data and displaing converted pressure.I did 't change any code,just I replaced LPS331AP by  LPS25HB chip.


Advice me is it nesassary to change any code ? or any calibration or offset vaules need to set?/
Please advice us...
