Find the temperature where you are. The temperature is measured in Celsius (metric). The micro:bit can find the temperature nearby by checking how hot its computer chips are.



  • a Number that means the Celsius temperature.

How does it work?

The micro:bit checks how hot its CPU (main computer chip) is. Because the micro:bit does not usually get very hot, the temperature of the CPU is usually close to the temperature of wherever you are. The micro:bit might warm up a little if you make it work hard, though!

Example: micro:bit thermometer

The following example uses temperature and show number to show the temperature of the room.

basic.forever(() => {
    let temp = input.temperature()

Example: Fahrenheit thermometer

This program measures the temperature using Fahrenheit degrees. Fahrenheit is a way of measuring temperature that is commonly used in the United States. To make a Celsius temperature into a Fahrenheit one, multiply the Celsius temperature by 18, divide by 10 and add 32.

basic.forever(() => {
    let c = input.temperature()
    let f = (c * 18) / 10 + 32

Try comparing the temperature your micro:bit shows to a real thermometer in the same place. You might be able to figure out how much to subtract from the number the micro:bit shows to get the real temperature. Then you can change your program so the micro:bit is a better thermometer.
