CPU Temperature Information

The WalnutPi 1B's H616/H618 SoC features 4 built-in temperature sensors:

  • sensor0: CPU Temperature
  • sensor1: GPU Temperature
  • sensor2: VE (Video Encoding) Temperature
  • sensor3: DDR Temperature
Note

The temperature values obtained from the commands below need to be divided by 1000.
