Onboard temperature

Read the processor's approximate temperature and watch it change slowly.

Lesson goal: Display input.temperature() in degrees Celsius every two seconds and understand why it is an approximation.

Section 1

Understand

  • approximate sensor
  • Celsius
  • sampling interval
  • data log
  • 1input.temperature gives a rough °C from the processor.
  • 2It is not a precise room thermometer, and not the kit's LM35.
  • 3Never heat the board to test it.

Safety first

  • Do not heat the board with a hair dryer, lamp, radiator or flame, and do not put it in a fridge or freezer. Change location gently instead, for example a cooler room.
