How to check the temperature?

Is there a way to measure the temperature of the Rock Pi S?
I’ve tried lm-sensors and watch tools in Debian, but it says it can’t find any sensors.

Hello haste,

Use command sudo cat /sys/class/thermal/thermal_zone0/temp can get a value that third power of 10 multiply CPU temperature(Centigrade).


The output of the command is 38181. So does that mean my SoC is at 38.181C?
It feels cool on the outside, not like it’s 38C!
Perhaps that’s the junction temperature?
