Intelligent sensor

From Wikipedia, the free encyclopedia
Jump to navigation Jump to search

An intelligent sensor is a sensor that takes some predefined action when it senses the appropriate input (light, heat, sound, motion, touch, etc.).


The sensor has to do the following tasks:

  • Give a digital signal.
  • Be able to communicate the signal.
  • Be able to execute logical functions and instructions.

Elements of Intelligent sensors[edit]

  • Primary sensing element
  • Excitation control
  • Amplification
  • Analogue filtering
  • Data conversion
  • Compensation
  • Digital information processing
  • Digital communication processing

Technical capacities[edit]

Because the tasks are performed by microprocessors, any gadget which mixes a sensor and a microprocessor is usually called an intelligent sensor.

To qualify as an intelligent sensor, the sensor and processor must be part of the same physical unit. A sensor whose only function is to detect and send an unprocessed signal to an external system which performs some action is not considered intelligent.

Ubiquitous Sensor Networks (USN)[edit]

Ubiquitous Sensor Networks (USN) is used to describe a network of intelligent sensors that could, one day, become ubiquitous.[1]
