Ideas

The CPU temperature information of the Raspberry Pi is located in the file /sys/class/thermal/thermal_zone0/temp, which is a read-only file; we can read the value and convert it to the actual temperature.

Get temperature parameters

Open the terminal and run the following two commands to obtain the temperature parameters:


xxxxxxxxxx
cd /sys/class/thermal/thermal_zone0
cat temp

T_{a c t u a l t e m p e r a t u r e} = \frac{t e m p e r a t u r e p a r a m e t e r}{1000}
