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 

这个不一样设备获得的结果多是不已样的，有这样的：

还有压根就不能执行的状况。

 

我的理解，这个就是对应不一样设备的温度传感器。

而后，咱们能够看到，有的传感器是针对CPU的。那么到下面的目录：

shell@android:/sys/class/thermal $

你能够找到这些传感器，而后进入对应的传感器，用cat指令能够知道温度了。

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

## cat type 的话应该能够获取传感器的类型信息。

 

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