How to find out Raspberry Pi GPU and ARM CPU temperature on Linux nixCraft Updated Tutorials/Posts

I am using a Raspberry PI 2/3 credit size computer. How do I find out my Raspberry PI GPU or CPU temperature from Linux operating system command line option? How do I monitor the core temperature of my Raspberry Pi 3?

The Raspberry Pi is a small and affordable computer for student and hobbyist. You can us it to learn programming, Linux, sysadmin and devops stuff. One can easily find out the Raspberry Pi GPU and ARM CPU core temperature using the following commands.

Show Raspberry Pi GPU temperature

Open the Terminal application and type the following command to view GPU (Graphics Processing Unit) temperature:
vcgencmd measure_temp
/opt/vc/bin/vcgencmd measure_temp
Sample output:

Display Raspberry Pi ARM CPU temperature

Type the following cat command:
cat /sys/class/thermal/thermal_zone0/temp
Divide it by 1000 to get the ARM CPU temperature in more human readable format:

echo "$((cpu/1000)) c"

Sample outputs:

Raspberry Pi get temperature – Putting it all together

Create a simple bash script called to see both ARM CPU and GPU temperature of Raspberry Pi. Type the following command:
Append the following code:

# Script:
# Purpose: Display the ARM CPU and GPU temperature of Raspberry Pi 2/3 
# Author: Vivek Gite <> under GPL v2.x+
# -------------------------------------------------------
echo "$(date) @ $(hostname)"
echo "-------------------------------------------"
echo "GPU => $(/opt/vc/bin/vcgencmd measure_temp)"
echo "CPU => $((cpu/1000))'C"

Save and close the file. Set permission:
chmod +x
Run it as follows:
Sample outputs:

GPU => temp=44.4'C
CPU => 44'C


This page explained how to monitor the core temperature of your Raspberry Pi. For more info see this page.
