MIS2DH相对加速度测量如何使用

你好
我正在研究一个项目，我必须测量相对于万有引力的加速度。当任何方向的相对加速度大于x mg时，我想得到警报。我已经尝试使用高通滤波器和点击功能构建，但我没有得到预期的结果。有人知道我如何使用传感器功能的构建来实现这个功能吗？
我还有第二个与传感器有关的问题：
当我使用内置传感器测量温度时，我得到的值是8位二进制补码，左对齐，但我还没有发现如何将它们转换为实际温度。在正常的加热房间里，我大多得到大约-3或-4的值（从二进制补码转换成小数）。温度范围为-40至85℃。

Hi
I�m working on a projekt where I have to measure the acceleration relative to the gravitation. I want to get an alert when there is an relative acceleration in any direction greater than x mg. I have tried with the build in high-pass filter and the click function, but I didn�t get results as expected. Does someone have an idea how i can use the build in functions of the sensor to get this working?
And I have a second question related to the sensor:
When i measure the temperature with the build in sensor, I get the values as 8bit two�s complement, left justified, but I haven�t found out how to convert them to the real temperature. I mostly get values of about -3 or -4 (converted from two�s complement into decimal) in a normal heated room. The temperature range is -40 to 85.
