  • Android 如何获取CPU的温度

    最近的项目有需求要获取CPU的温度,在网上找了一些资料,基本算是解决了问题:

    进入adb shell执行下面的命令:

    shell@android:/ $ cat /etc/thermald.conf 

    这个不同设备得到的结果可能是不已样的,有这样的:

    sampling         5000

    还有压根就不能执行的情况。

    个人理解,这个就是对应不同设备的温度传感器。

    然后,我们可以看到,有的传感器是针对CPU的。那么到下面的目录:

    shell@android:/sys/class/thermal $

    你可以找到这些传感器,然后进入对应的传感器,用cat指令可以知道温度了。

    shell@android:/sys/class/thermal/thermal_zone7 $ cat temp

    ## cat type 的话应该可以获取传感器的类型信息。

    虽然解决了问题,但是不是很理解。比如,这个是linux系统的通用设置吗? 其他传感器都对应了什么? 等等。
