WMI error

[cosmin1805]

Hi, I am trying to run this thing to get the CPU temperature(I got it from youtube but I am open to other suggestions that work on WINDOWS) and I get this error.

import wmi
w_temp=wmi.WMI(namespace="root\\wmi")
print((w_temp.MSAcpi_ThermalZoneTemperature()[0].CurrentTemperature/10.0)-273.15)

Error:

Many CPU producers wouldn't provide a way so wmi can acess temperature directly.
Can use Open Hardware Monitor and call it trough wmi.

import wmi

w = wmi.WMI(namespace="root\OpenHardwareMonitor")
temperature_infos = w.Sensor()
#print(temperature_infos)
for sensor in temperature_infos:
    #print(sensor)
    if sensor.SensorType == 'Temperature':
        print(sensor.Name)
        print(sensor.Value)

Output:

Thank you so much this made me realize that when I tried this method I installed OpenHardware monitor in my project folder and used namespace="root\OpenHardwareMonitor".....
