最近的項目有需求要獲取CPU的溫度，在網上找了一些資料，基本算是解決了問題：
進入adb shell執行下面的命令：
shell@android:/ $ cat /etc/thermald.conf
這個不同設備得到的結果可能是不已樣的，有這樣的：

還有壓根就不能執行的情況。
個人理解，這個就是對應不同設備的溫度傳感器。
然后，我們可以看到，有的傳感器是針對CPU的。那么到下面的目錄：
shell@android:/sys/class/thermal $
你可以找到這些傳感器，然后進入對應的傳感器，用cat指令可以知道溫度了。
shell@android:/sys/class/thermal/thermal_zone7 $ cat temp
## cat type 的話應該可以獲取傳感器的類型信息。
雖然解決了問題，但是不是很理解。比如，這個是linux系統的通用設置嗎？ 其他傳感器都對應了什么？ 等等。
