Intelligent sensor 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 microprocessor

Microprocessor

A microprocessor incorporates the functions of a computer's central processing unit on a single integrated circuit, or at most a few integrated circuits. It is a multipurpose, programmable device that accepts digital data as input, processes it according to instructions stored in its memory, and...

s, any gadget which mixes a sensor and a microprocessor is usually called as 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.
