SENSOR HAVING ENHANCED DETECTION CAPABILITY

摘要

A sensor according to the present embodiment comprises: a light provision unit comprising a light-emitting device for providing an optical stimulus, and a first controllable power source for providing driving power to the light-emitting device; a light detection unit comprising a light-receiving device for detecting an optical response to the optical stimulus and then outputting same as an electric signal, and a second controllable power source for providing driving power to the light-receiving device; and a control unit for controlling the driving powers provided by the first controllable power source and the second controllable power source.
