Thermometer
An instrument that measures temperature
Real World Example
Imagine trying to decide what to wear based on the weather outside. Just as you check the sky and feel the air to gauge if a jacket is needed, a thermometer measures temperature by responding to changes in its environment. The thermometer acts like your senses, detecting how hot or cold it is, and then provides a clear readout, just as you make a decision based on your observations.
