Android 如何獲取CPU的溫度

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 

這個不一樣設備獲得的結果多是不已樣的，有這樣的：

還有壓根就不能執行的狀況。

 

我的理解，這個就是對應不一樣設備的溫度傳感器。

而後，咱們能夠看到，有的傳感器是針對CPU的。那麼到下面的目錄：

shell@android:/sys/class/thermal $

你能夠找到這些傳感器，而後進入對應的傳感器，用cat指令能夠知道溫度了。

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

## cat type 的話應該能夠獲取傳感器的類型信息。

 

雖然解決了問題，可是不是很理解。好比，這個是linux系統的通用設置嗎？ 其餘傳感器都對應了什麼？ 等等。
