Questions tagged [temperature]

A simple definition of temperature is that it is a measure of heat dissipation, This tag can include programming related questions like temperature conversion, temperature detection through device sensors etc.

The temperature of a device is a quantitative measure which indicates how hot or cold the device is, temperature sensitive sensors can be used to make an alarming signal and can be programmed in various programming languages. It is measured by detection of heat radiation by a temperature sensing material, which may be then calibrated in any of various temperature scales, Celsius, Fahrenheit, Kelvin, etc.

Usage of Tag temperature

The tag temperature on stackoverflow can be used to ask questions related to programming a device or application, to sense temperature of a room/device. Tag temperature should be only used for questions related to programming, Please do not ask here questions related to physics or thermodynamics.
