Temperature
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.
input.temperature();
Returns
- a Number that means the Celsius temperature.
How does it work?
The BBC 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()
basic.showNumber(temp)
})
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 1.8 and add 32.
basic.forever(() => {
let c = input.temperature()
let f = (c * 1.8) + 32
basic.showNumber(f)
})
~hint
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.
