Getting CPU temperature using Python?

Question

How do I retrieve the temperature of my CPU using Python? (Assuming I'm on Linux)

Answer 1

There is anewer "sysfs thermal zone" API (see also LWN article and Linux kernel doc ) showing temperatures under eg

/sys/class/thermal/thermal_zone0/temp

Readings are in thousandths of degrees Celcius (although in older kernels, it may have just been degrees C).

Answer 2

I recently implemented this in psutil for Linux only.

>>> import psutil
>>> psutil.sensors_temperatures()
{'acpitz': [shwtemp(label='', current=47.0, high=103.0, critical=103.0)],
 'asus': [shwtemp(label='', current=47.0, high=None, critical=None)],
 'coretemp': [shwtemp(label='Physical id 0', current=52.0, high=100.0, critical=100.0),
              shwtemp(label='Core 0', current=45.0, high=100.0, critical=100.0),
              shwtemp(label='Core 1', current=52.0, high=100.0, critical=100.0),
              shwtemp(label='Core 2', current=45.0, high=100.0, critical=100.0),
              shwtemp(label='Core 3', current=47.0, high=100.0, critical=100.0)]}

Answer 3

If your Linux supports ACPI, reading pseudo-file /proc/acpi/thermal_zone/THM0/temperature (the path may differ, I know it's /proc/acpi/thermal_zone/THRM/temperature in some systems) should do it. But I don't think there's a way that works in every Linux system in the world, so you'll have to be more specific about exactly what Linux you have!-)

Answer 4

Reading files in /sys/class/hwmon/hwmon*/temp1_* worked for me but AFAIK there are no standards for doing this cleanly. Anyway, you can try this and make sure it provides the same number of CPUs shown by " sensors " cmdline utility, in which case you can assume it's reliable.

from __future__ import division
import os
from collections import namedtuple


_nt_cpu_temp = namedtuple('cputemp', 'name temp max critical')

def get_cpu_temp(fahrenheit=False):
    """Return temperatures expressed in Celsius for each physical CPU
    installed on the system as a list of namedtuples as in:

    >>> get_cpu_temp()
    [cputemp(name='atk0110', temp=32.0, max=60.0, critical=95.0)]
    """
    # http://www.mjmwired.net/kernel/Documentation/hwmon/sysfs-interface
    cat = lambda file: open(file, 'r').read().strip()
    base = '/sys/class/hwmon/'
    ls = sorted(os.listdir(base))
    assert ls, "%r is empty" % base
    ret = []
    for hwmon in ls:
        hwmon = os.path.join(base, hwmon)
        label = cat(os.path.join(hwmon, 'temp1_label'))
        assert 'cpu temp' in label.lower(), label
        name = cat(os.path.join(hwmon, 'name'))
        temp = int(cat(os.path.join(hwmon, 'temp1_input'))) / 1000
        max_ = int(cat(os.path.join(hwmon, 'temp1_max'))) / 1000
        crit = int(cat(os.path.join(hwmon, 'temp1_crit'))) / 1000
        digits = (temp, max_, crit)
        if fahrenheit:
            digits = [(x * 1.8) + 32 for x in digits]
        ret.append(_nt_cpu_temp(name, *digits))
    return ret

Answer 5

Py-cputemp似乎可以完成这项工作。

Answer 6

Look after pyspectator in pip

Requires python3

from pyspectator import Cpu
from time import sleep
cpu = Cpu(monitoring_latency=1)

while True:
    print (cpu.temperature)
    sleep(1)

Answer 7

Depending on your Linux distro, you may find a file under /proc that contains this information. For example, this page suggests /proc/acpi/thermal_zone/THM/temperature .

Answer 8

作为替代方案，您可以安装 lm-sensors 包，然后安装PySensors （用于 libsensors 的 Python 绑定）。

Answer 9

你可以试试PyI2C模块，它可以直接从内核中读取。

Answer 10

Sysmon works nice. Nicely made, it does much more than measure CPU temperature. It is a command line program, and logs all the data it measured to a file. Also, it is open-source and written in python 2.7.

Answer 11

I would reflect on SDsolar 's solving above, modified the code a bit., and now it shows not only one value. Until the while loop you gets continuously the actual value of the CPUs temperature

On linux systems:

Install the pyspectator module:

pip install pyspectator

Put this code into a file 'cpu-temp.py'

#!/usr/bin/env python3
from pyspectator.processor import Cpu
from time import sleep

while True:
    cpu = Cpu(monitoring_latency=1) #changed here
    print (cpu.temperature)
    sleep(1)

Answer 12

For Linux systems(Tried on Ubuntu 18.04)

Install the acpi module by sudo apt install acpi

Running acpi -V should give you a ton of info about your system. Now we just need to get the temperature value via python.

import os
os.system("acpi -V > output.txt")
battery = open("output.txt", "r")
info = battery.readline()
val = info.split()
percent4real = val[3]
percentage = int(percent4real[:-1])
print(percentage)

The percentage variable will give you the temperature. So, first we take the output of the acpi -V command in a text file and then read it. We need to convert it into an integer since the data is all in String type.

• Note: This command does not display CPU temperature when used in WSL
