The Microbit is a small computer (or microcontroller) that can sense things around it —
like temperature. It has a built-in temperature sensor that measures how hot or cold it is.
But here’s something interesting: it doesn’t directly measure air temperature —
it measures the temperature of its own processor (the chip inside it).
This means the reading might be a little warmer than the actual room temperature,
especially if the Microbit has been running for a while.
