Max operating temperature of Raspberry Pi is 85°C.
If the temperature exceeds 82°C, then the CPU’s clock speed will be slowed until the temperature drops below 82°C.
So it is very important to monitor the temperature of the board and Raspberry Pi has a built-in sensor for this.
In this note i will show how to check the CPU/GPU temperature of Raspberry Pi.
Cool Tip: Shutdown & reboot Raspberry Pi safely! Read more →
Check Temperature of Raspberry Pi
Measure the GPU temperature:
$ vcgencmd measure_temp
– or –
Check the CPU temperature:
$ echo temp=$((`cat /sys/class/thermal/thermal_zone0/temp`/1000)).0\'C
The CPU/GPU temperature of Raspberry Pi can be monitored using
For example, to show the GPU temperature of Raspberry Pi each 5 seconds, execute:
$ watch -n5 vcgencmd measure_temp
