: The [[Scientist|scientist's]] '''data logger''' and light probe showed the brightness of the [[light]] in the [[laboratory]].
==Key Stage 3==
===Meaning===
[[File:DataLogger.png|right|300px|thumb|A '''data logger''' that can measure temperature, sound level and light level.]]
A '''data logger''' is a small computer that can be attached to different sensors to [[measure]] different physical quantities over [[time]].
===About Data Loggers===
: '''Data loggers''' have different sensors that can be attached to [[measure]] different things.
: The sensors you may use are:
:*A [[temperature]] sensor.
:*A sensor which [[measure]]s the [[Volume (Space)|volume]] of [[sound]].
:*A that can [[measure]] how bright the [[light]] is.
:*[[Light Gate]]s which can [[measure]] the [[speed]] of an [[object]] and the [[time]] taken between the [[Light Gate|light gates]].
