My customers are planning to use ADXL356's temperature sensor for more accurate acceleration.
However, the plan is difficult.
Do you have any useful knowledge for us?
The customer first tried to evaluate the temperature sensor.
However, the value output by the temperature sensor seems to be different from the temperature of the air as well as the temperature of the PCB board surface.
The thermo camera may be useful, but it seems that the accuracy is insufficient.
Currently, the output of the temperature sensor seems to be only several degrees below the temperature of the PCB substrate surface.
Is this a common thing?
We thought that the temperature sensor on the die would output a value higher than the temperature of the PCB substrate surface.
If we successfully overcome this problem, we plan to think of a way to calibrate the acceleration by the output of the temperature sensor.
I believe that we would benefit greatly from your expertise.
Please lend me your wisdom.
