3.14. Temperature sensor

1) H618 has a total of 4 temperature sensors, the command to view the temperature is as follows: The displayed temperature value needs to be divided by 1000, the unit is Celsius.

a. sensor0: CPU temperature sensor, the first command is used to view the type of temperature sensor, and the second command is used to view the value of the temperature sensor

orangepi@orangepi:~$ cat /sys/class/thermal/thermal_zone0/type
cpu_thermal_zone
orangepi@orangepi:~$ cat /sys/class/thermal/thermal_zone0/temp

b. sensor1: DDR temperature sensor, the first command is used to view the type of temperature sensor, and the second command is used to view the value of the temperature sensor

orangepi@orangepi:~$ cat /sys/class/thermal/thermal_zone1/type
ddr_thermal_zone
orangepi@orangepi:~$ cat /sys/class/thermal/thermal_zone1/temp

c. sensor2: GPU temperature sensor, the first command is used to view the type of temperature sensor, the second command is used to view the value of the temperature sensor

orangepi@orangepi:~$ cat /sys/class/thermal/thermal_zone2/type
gpu_thermal_zone
orangepi@orangepi:~$ cat /sys/class/thermal/thermal_zone2/temp

d. sensor3: VE temperature sensor, the first command is used to view the type of temperature sensor, and the second command is used to view the value of the temperature sensor

orangepi@orangepi:~$ cat /sys/class/thermal/thermal_zone3/type
ve_thermal_zone
orangepi@orangepi:~$ cat /sys/class/thermal/thermal_zone3/temp

2) The system with Linux6.1 kernel can also use the sensors command to view the current temperature of the system

orangepi@orangepi:~$ sensors
cpu_thermal-virtual-0
Adapter: Virtual device
temp1: +47.4°C (crit = +110.0°C)
gpu_thermal-virtual-0
Adapter: Virtual device
temp1: +48.7°C (crit = +110.0°C)

ddr_thermal-virtual-0
Adapter: Virtual device
temp1: +47.8°C (crit = +110.0°C)
ve_thermal-virtual-0
Adapter: Virtual device
temp1: +47.2°C (crit = +110.0°C)
