Python Question

Get CPU temperature in python on windows

Basically i want to read the cpu temperature in python. Please explain in layman's terms as i have never done this on windows before nor have i had to work with wmi.

This is what I have at the moment:

import wmi
w = wmi.WMI(namespace="root\wmi")
temperature_info = w.MSAcpi_ThermalZoneTemperature()[0]
print temperature_info.CurrentTemperature


(i got this code from this thread: Accessing CPU temperature in python)

however, on running the script, i get this error:

Traceback (most recent call last):
File "C:\Users\Ryan\Desktop\SerialSystemMonitor", line 4, in <module>
temperature_info = w.MSAcpi_ThermalZoneTemperature()[0]
File "C:\Python27\lib\site-packages\wmi.py", line 819, in query
handle_com_error ()
File "C:\Python27\lib\site-packages\wmi.py", line 241, in handle_com_error
raise klass (com_error=err)
x_wmi: <x_wmi: Unexpected COM Error (-2147217396, 'OLE error 0x8004100c', None, None)>


what can i do to get this to work?

Answer

According to the MSDN page on WMI Error Constants, the error you have received is:

WBEM_E_NOT_SUPPORTED
2147749900 (0x8004100C)

Feature or operation is not supported.

Presumably, then, your CPU does not provide temperature information through WMI. If your CPU doesn't expose this information, you're probably out of luck, at least as far as a straightforward solution in Python goes.

I assume you've tried the other option given in the answer you linked, using Win32_TemperatureProbe(); if you haven't, try it.
