智能手机中的传感器
我想了解加速度计、压力传感器、光传感器等传感器在智能手机中的实际工作原理。假设我们在 Android 中为加速度计设置了 onSensorChanged，为了渲染输出，内部实际上发生了什么。
任何人都可以帮助我找到有关此问题的资源吗？
提前致谢，
I would like to learn on how the sensors like accelerometer, pressure sensors, light sensors and the rest actually work in smartphones. Say if we have onSensorChanged for an accelerometer in android, what actually is happening internally in order to render the output.
Can anyone help with me with resources that I can find about this.
Thanks in advance,

了解硬件本身可能很有趣，但我发现有趣的是从传感器获取数据并使其有用的方法。这是一个完整的字段：http://en.wikipedia.org/wiki/Digital_signal_processing 也检查这个输出：http://www.dspguide.com
It might be interesting to learn about the hardware itself, but what I find intriguing are the methods for taking the data from the sensor and making it useful. It's a whole field: http://en.wikipedia.org/wiki/Digital_signal_processing also check this out: http://www.dspguide.com
您可以查看解释有关传感器的许多细节的技术讲座。该会议不仅提供了比平常更多的有关传感器的详细信息，而且还涵盖了一些有趣的主题，例如传感器集成。您可以在提供的链接中找到该视频
You can have a look to a technical talk explaining many details about sensors. The session no tonly gives more details than usual about sensors, but also covers some interesting topics such as sensor integration. You can find the video in the provided link
