Can I get Omega's CPU temperature?

Hi,
I apologize for my poor English.

I am looking for ways to acquire Omega 2 CPU temperature for the next project
I do not have knowledge of Linux and hardware, so it will be helpful if you explain briefly.
thank you

As far as I know - from reading the datasheets of both AR9331 (Omega1) and MT7688 (Omega2) - there is no temperature sensor in these SoCs that could be read.

Larger SoCs like those in the RaspberryPi do have temperature sensors, that can usually be read via /sys/class/thermal/...
(on a RPi, typing cat /sys/class/thermal/thermal_zone0/temp gives you the CPU temperature in 1/1000 degree celsius)

Thank you!
I thought that temperature could be acquired just like RPi, but learned that there is also SoC without sensor.
I will consider using a thermistor.
