Smart Q secondary sensor range

All warm objects emit infrared radiation. This sensor, therefore, can be used to detect the location of any warm item or living organism. When set to its most sensitive mode, the sensor can detect very low IR emissions, such as the heat trail left on a bench top after you move your hand away.

This multi-range sensor detects the energy from radiant sources from UV to Far Infrared.

The Infrared sensor adds another dimension to heat loss and energy transfer experiments, and can be seen used as a heat detector in the 'Find the Earthquake victims' activity in the video clip.

Applications:
Physics:
Investigating radiant from different surfaces e.g. heat from a Leslie's cube
Black body studies (radiance range)
Efficiency of insulation
Study inverse square law - verifying that heat radiation from source is inversely proportional to the square of its distance
Heat distribution along a metal rod
Hershel's discovery of infrared experiment
Investigating Stefan-Boltzmann's radiation law using a tungsten filament lamp Infrared in the environment
Illustration of non-contact thermometry
Biology:
Comparing warm and cold blooded animals
Where do we lose heat? (head, face, hands etc.)
General:
Locating a hot body e.g. a burnt match
Using infrared to locate a disaster victim*
Residual heat from different surfaces e.g. finger print on worktop*
Efficiency of electric light bulbs
