[[File:TimeSensor.jpg|thumb|The [[Third Doctor]]'s time sensor homes in on [[the Master]]. ([[DW]]: ''[[The Time Monster]]'')]]

A '''time sensor''' was a device which, according to [[Jo Grant]], "detect[ed] disturbances in the [[time field]]". It was most useful as a "[[TARDIS]] sniffer-outer", In particular, it was used by the [[Third Doctor]] to detect the presence of [[the Master's TARDIS]]. It was calibrated to provide distances to a disturbance in [[Venusian]] [[foot|feet]] and [[mile]]s. It was unknown whether this meant the time sensor was of Venusian origin, or if the Doctor invented the device and ''intentionally'' used Venusian units due to his fondness for that [[planet]].
