INTRODUCTION
A sensor that includes a microprocessor that conditions the signals before transmission to the control network.
It filters out unwanted noise and compensates for errors before sending the data.
Some sensors can be custom programmed to poduce alerts on their own when critical needs are reached.
Smart sensors are an extension of traditional sensors to those with advanced learning and adaptation capabilities.
These are sensors with integrated electronics that can do one or more functions such as making decisions, 2way communications.
There is one more form of smart sensor called smart plug and play transducer electronic data sheet (TEDS) sensors.
This iteration adds a limited amount of smartness to a sensor by embedding the TEDS into the device in a cost effective manner.
“A Smart sensor is a sensor version of smart transducer”.
A Smart transducer is “A transducer that provides functions beyond those necessary for generating a correct representation of a sensed or controlled quantity”.
The functions of an smart sensor system can be described as:
Compensation: Ability of the system to detect and respond to changes in the network environment.
Information processing : encompasses the data related processing to enhance and interpret the collected data and maximize the efficiency of the system.
Communications: component of sensor system incorporates the standardized network protocol which serves to links the distributed sensors in a coherent manner.
Integration: It involves the coupling of sensing and computation at the chip level.
Validation: required to avoid the potential disastrous effects of the propagation of the erroneous data.
Data fusion: techniques are required in order combine information from multiple sensors.
Smart Sensor Developer Kit
The Smart Sensor Developer Kit provides the first-ever user-configurable, active microsensor technology that can be easily and cheaply incorporated into a wide range of instruments for many applications
