Transducers are devices that convert one form of energy to another. Silicon can be used in smart sensors and transducers due to its piezoresistance and ability to detect various signals including light, force, temperature, and chemicals. Smart sensors integrate transduction elements with electronics, which provides advantages like smaller size, self-calibration, computation, communication, and multi-sensing capabilities.

This Presentation provides some basics of Sensors Technology.........
It gives few ideas to learn about sensors which are as normally used as electrical & electronics applications.......
Smart Sensors: Analyzing Efficiency of Smart Sensors in Public DomainDr. Amarjeet Singh
The paper gives the brief idea of smart sensors,
structure and its application. Smart sensor as compare to
other sensors can sensor anything with the special computing
devices connected with each other in sensor network. These
smart sensors first convert the digital signals to analog signals
and then communicate the message to the device. Now a days
smart sensors are used almost everywhere around us but very
few people know its working and future applications. So here
is a small review on smart sensors. This paper will help you
gain knowledge and its applications in daily life.
Sensors are at the core of every modern invention.
In these couple of slides I describe a couple of them and how they are connected to microcontroller pins.
DESIGN OF AN INTELLIGENT AND EFFICIENT LIGHT CONTROL SYSTEMEditor IJCATR
Recently, many researches has been carried out to save the energy in many aspects such
as producing a device which consumes very less energy or designing a system which helps to
reduce the power consumption using the existing devices. In this paper, a room light control system
is proposed which is named as light control system (LCS). This proposed system will able to
provide the needed light which provides the satisfaction of users and will provide energy saving
and management.
In this paper the Lighting Control System and the decision making algorithm, are
discussed. As per the algorithm the system will first check any occupant is there in the room. If so
then the system will check the intensity of light in the room and if it is low then it will switch on the
light.
Our proposed system can able to minimize the energy consumed for lighting in a room
and can able to provide it efficiently.

Smart Sensor Configuration for Security System Automation Using FPGAIJTET Journal
Abstract--- Automation in industrial control and monitoring systems plays a vital role in maintaining smooth work environment and handling perilous situation that may occur in work area. The available systems mostly use physical cables for signal transfer between the sensors and the control system. These systems have some significant problems such as the cable installation and maintenance costs associated with moving and replacement of cables during machinery maintenance, configuration and re-configuration. While the technological evolution of sensors is reflected in sensors getting smart, small, light weight, and cheapest, another key development is taking place in the sensors industry in the growth of wireless sensor use in industrial applications. The proposed wireless sensor-based controls provide industry attention in order to reduce costs, better power management and ease in maintenance. Wireless sensors have been successfully implemented in many industrial applications because of its performance, monitoring, security development and control the sensor system etc.

5. WHAT IS MEANT BY TRANSDUCER?....
TRANSDUCER IS DEFINED AS A DEVICE
THAT RECEIVES ENERGY FROM ONE
SYSTEM AND TRANSMITS TO ANOTHER.
(WHICH CONVERTS PHYSICAL QUANTITY
INTO ELECTRICAL SIGNAL)IT’S ALSO CALLED
AS ‘PICKUP’
6. [Sensor means which detects/measures the
device
Example: thermometer
SMART SENSOR WITH INTEGRATED
ELECTRONICS THAT CAN PERFORM ONE
OR MORE OF THE FOLLOWING
FUNCTION….
LOGIC FUNCTIONS
TWO WAY COMMUNICATION
MAKE DECISIONS…..
8. a transduction element either includes thin
metal films,zinc oxide & polymeric films
integrated sensors provide significant
advantages in terms of overall sizes & the
ability to use small signals from the
transduction element.
IC (integrated circuit) industry will get
involved in smart sensor if a very large market
can be captured &the production of smart
sensor doesn’t require non-standard
processing steps…..
9. Signal domain examples
Radiant Light intensity,polarization,phase,
wavelength
mechanical Force,pressure,flow,vaccum,
thickness
thermal Temperature,temp gradient,thickness
chemical Concentration,toxicity,pH
magnetic Field intensity,flux
10. Signal domain examples
Radiant Photo voltaic effect,photo electric
effect,photo magneto-electric
effect,photo conductivity
mechanical Piezo resistivity
thermal Seebeck effect,temperatre
dependence of conductivity
11. Radian signal domain:Radiant
silicon can be used to connect a sensor
for sensing wide range of radiant signal
from gamma rays to infrared. Silicon can
be used for the fabrication of
photoconductors,phototransistor or to
detect nuclear radition.
12. silicon can be used for measuring force
and pressure because of the piezo resistance
effect.
This effect is large because the average
mobility of electrons and holes in siliconis
strongly affected by the application of strain
silicon can alo be used for the
measurement of air or gas velocities.
13. Smart sensor also enhances the following
applications:
self calibration- adjusting some parameter of
sensor during fabrication.
-calibration is needed bcoz, their
adjustments usually change with the time that
needs the device to be removed
& recalibrated.thee problems are solved by smart
sensor(has the the correction functions in memory).
14. computation- it also allows one to obtain the
average, varience & standard deviation for set
of measurement.this can be easily done done
using smart sensor
- to compensate for the environmental
change such as temperature.
communication- communication means of
exchanging or conveying information.
15. multisensing – a single smart sensor can
measure pressure ,temperature,humidity, gas
flow &infra red….
System reliability
System reliability is significantly improved
due to the utilization of smart sensors
16. Non linearity
Cross sensitive(shows an un desairable
sensitivity to strain &temperature )
Offset(well reduced by sensitivity reduction
method)
Parameter drift & componeent values(these
are functions of time it can be solved by
automatic calibration)
17. Thermal signal domain- measurement of
temperature by using two bipolar transistors
with a cons.ratio of emitter current.
Magnetic signal domain-silicon is a non
magnetic material. But it can be used for the
construction of hallplates &transistor
structure that are sensitive to magnetic fields.
Chemical signal domain-ISFET is suitable for
such application.
18. The presence in smart sensor has led to
corrections for different un desirable sensor
characteristics which include,
input offset &span variation, non linearity &
cross sensitivity .as these are carried in
software no additional software is required
thus calibration becomes an electronic
process
19. Sensor inside hardware is more complex in
the sensor on the other hand it is outside the
sensor.
Reduced cost of bulk cables & connectors
To reduce the cost of bulk cables & connectors
needed to connect different blocks
