hi:

I want to know where the following temperature types are monitored for temperature.

Now our board needs to read a temperature and determine the high-temperature state. So, which type should I use

agi@tegra-ubuntu:~$ cat /sys/class/thermal/thermal_zone0/type 
tj-thermal
agi@tegra-ubuntu:~$ cat /sys/class/thermal/thermal_zone1/type  
gpu-thermal
agi@tegra-ubuntu:~$ cat /sys/class/thermal/thermal_zone2/type  
cpu-thermal
agi@tegra-ubuntu:~$ cat /sys/class/thermal/thermal_zone3/type  
soc012-thermal
agi@tegra-ubuntu:~$ cat /sys/class/thermal/thermal_zone4/type  
soc345-thermal
agi@tegra-ubuntu:~$

Hi mingming,

There are several temperatures sensors for those thermal zone.
It depends on your use case and the requirement.

Please refer to Jetson Thor Product Family — BSP-specific Thermal Zones for details.
