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：

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。
