Temperature Information

The Walnut Pi 2B's T527 chip has 6 temperature sensors:

  • sensor0: CPUL (Little Core) temperature
  • sensor1: CPUB (Big Core) temperature
  • sensor2: GPU temperature
  • sensor3: NPU temperature
  • sensor4: DDR temperature
  • sensor5: PMIC temperature
Note

Temperature values retrieved by the commands below need to be divided by 1000.
