How to Monitor the CPU Temperature of Raspberry PI using Python Script?

Raspberry PI does not have any fans – although you can either install cooling chips or CPU/Central Processing Unit fans.

CPU Fan for Raspberry PI 4b

It would be great to monitor the temperature in case it gets too hot. The working temperature is less than 80 degree for raspberry PI. With a CPU fan, I managed to keep the CPU fan of the Raspberry PI cool with less than 30 degree.

Here is a python script that allows you to print the temperature of the CPU for raspberry PI:

import os
import time

def temperature_of_raspberry_pi():
    cpu_temp = os.popen("vcgencmd measure_temp").readline()
    return cpu_temp.replace("temp=", "")

while True:
    print(temperature_of_raspberry_pi())
    time.sleep(1)

The python script reports the temperature every second. You can run this in background and add some actions if temperature gets too high e.g. sending a email notification.

if temperature_of_raspberry_pi > 80:
    print("CPU Temperature too high!")
