Infrared thermometer

An infrared thermometer is like a magic wand that can measure the temperature of things without actually touching them. Think of it like taking someone’s temperature to see if they have a fever, but instead of using a thermometer that goes under their tongue or in their ear, we just point the infrared thermometer at their forehead from a distance.

When we point the infrared thermometer at something, like a person’s forehead, it sends out a beam of light that bounces off the object and then comes back to the thermometer. The thermometer then reads the temperature of the object based on the light that bounced back.

The thermometer has a special sensor that can detect the infrared light, which is like heat that we can’t see. Each object on Earth gives off different amounts of infrared light depending on how hot or cold it is.

So, the infrared thermometer helps measure how hot or cold something is without even touching it. It is helpful because it can take a temperature without spreading germs or disturbing the surface of the object - just like magic!
