Temperature value code

[20AJ0931]

Hi! I am new to python and I only know Arduino. I am building a laptop overheating detector and I somehow need to transfer temperature values from the sensors installed in my laptop to a Arduino board via a serial port. I figured out I can use PySerial. But I don't know how to get those temperature values. Can someone write a code for me please. I would be really thankful. Thank You

Hello,
as you have stated, before sending values to arduino you need to get temperature values. So you should know where they are stored and how they are accessed.
Although we have a forum member who seems to like writing code for users, I wouldn't expect someone will do that for you. Except perhaps pseudo code/algorithm outline, if that is fine for you.
But you can get great help with more specific (Python) questions here.

Very OS dependent... in Linux they are readibly available by reading the adequate pseudo-file:

>>> with open('/sys/class/hwmon/hwmon0/temp1_input') as t:
...     print 'Temps is %3.2f°C' % (float(t.read())/1000.)
... 
Temps is 43.00°C

Likely more complicated on Windows.

See pyspectator. I came across this two weeks ago. Didn't manage to see the temp here. Perhaps I have to turn on acpi

pyspectator look okay,did't work for temp reading on my laptop with Windows.

Here what i done before for Windows,this get all info by using Open Hardware Monitor.
Call call it trough wmi module like this.

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)

So temp for my laptop:

Output:
CPU Package
56.0
GPU Core
0.0
CPU Core #1
52.0
Temperature
35.0
CPU Core #2
56.0

My OS is Windows 10 Home. Besides what is this Open Hardware Monitor all about. I hear a lot of people talking about it.

Hmm there homepage dos explain it.

The Open Hardware Monitor is a free open source software
that monitors temperature sensors, fan speeds, voltages, load and clock speeds of a computer.

Because it's open source it's possible for languages like Python to get info from it.

Can you only derive a certain value like Temperature or will you get all the values. I only need the Temperature values and then maybe I can send them to Arduino.

[wavic]

psutil.sensors_temperatures() ?

[snippsat]

psutil.sensors_temperatures() ?

psutil is good,but temperatures you see in Doc

Availability: Linux

So do not work for Windows.

Can you only derive a certain value like Temperature or will you get all the values.

You can get all info that that OpenHardwareMonitor has,
but remember that you must run run "OpenHardwareMonitor.exe".
Code is taking info from it when it running in background.
