An intelligent sensor is a sensor that takes some predefined action when it senses the appropriate input (light, heat, sound, motion, touch, etc.).
Description
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
* Primary sensing element
* Excitation control
* Amplification
* Analogue filtering
* Data conversion
* Compensation
* Digital information processing
* Digital communication processing
Technical capacities
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)
Ubiquitous Sensor Networks (USN) is used to describe a network of intelligent sensors that
could, one day, become
ubiquitous.
