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