INTRODUCTION TO SENSOR
What is sensor?
Sensors are sophisticated devices that are frequently used to detect and respond to electrical or optical signals. A Sensor converts the physical parameter (for example: temperature, blood pressure, humidity, speed, etc.) into a signal which can be measured electrically. Let’s explain the example of temperature. The mercury in the glass thermometer expands and contracts the liquid to convert the measured temperature which can be read by a viewer on the calibrated glass tube.
Definition:
A sensor is a device that measures a physical quantity and converts it into a signal which can be read by an observer or by an instrument. For example, a mercury-in-glass thermometer converts the measured temperature into expansion and contraction of a liquid which can be read on a calibrated glass tube. A thermocouple converts temperature to an output voltage which can be read by a voltmeter. For accuracy, all sensors need to be calibrated against known standards. ( OR )
Sensor is the device which converts any physical quantity to its equivalent electrical signal. There are different types of sensor are available there are: Temperature sensor, Light sensor, Voltage sensor, Smoke Sensor, Gas sensor, Fire sensor, Magnetic Sensors, etc.
Sensor deviations :
If the sensor is not ideal, several types of deviations can be observed:
The sensitivity may in practice differ from the value specified. This is called a sensitivity error, but the sensor is still linear.
Since the range of the output signal is always limited, the output signal will eventually reach a minimum or maximum when the measured property exceeds the limits. The full scale range defines the maximum and minimum values of the measured property.
If the output signal is not zero when the measured property is zero, the sensor has an offset or bias. This is defined as the output of the sensor at zero input.
If the sensitivity is not constant over the range of the sensor, this is called nonlinearity. Usually this is defined by the amount the output differs from ideal behavior over the full range of the sensor, often noted as a percentage of the full range.
If the deviation is caused by a rapid change of the measured property over time, there is a dynamic error. Often, this behavior is described with a bode plot showing sensitivity error and phase shift as function of the frequency of a periodic input signal.
If the output signal slowly changes independent of the measured property, this is defined as drift (telecommunication).
INTRODUCTION
Energy is the ability to do work. While energy surrounds us in all aspects of life, the
ability to harness it and use it for constructive ends as economically as possible is the challenge
before mankind. Alternative energy refers to energy sources, which are not based on the burning
of fossil fuels or the splitting of atoms. The renewed interest in this field of study comes from the
undesirable effects of pollution (as witnessed today) both from burning fossil fuels and from
nuclear waste byproducts. Fortunately there are many means of harnessing energy, which have
less damaging impacts on our environment in India.
EXISTING SYSTEM:
Other people have developed Rack-pinion and pulley (mechanical-to-electrical) surfaces
in the past, but the Crowd Farm has the potential to redefine urban space by adding a sense of fluidity and
encouraging people to activate spaces with their movement. The Crowd Farm floor is composed
of standard parts that are easily replicated but it is expensive to produce at this stage. This
technology would facilitate the future creation of new urban landscapes athletic fields with a spectator
area, music halls, theatres, nightclubs and a large gathering space for rallies, demonstrations and
celebrations, railway stations, bus stands, subways, airports etc. like capable of Harnessing
human location for electricity generation.
PROPOSED SYSTEM:
Proposal for the utilization of waste energy of foot power with human locomotion is very
much relevant and important for highly populated countries like India and China where the
roads, railway stations, bus stands, temples, etc. are all over crowded and millions of people
move around the clock. This whole human/bio energy being wasted if can be made possible for
utilization it will be great invention and crowd energy farms will be very useful energy sources
in crowded countries. Walking across a "Crowd Farm," floor, then, will be a fun for idle people who
can improve their health by exercising in such farms with earning. The electrical energy generated at
such farms will be useful for nearby applications.
CONCLUSION
The project “FOOT STEP POWER GENERATION FOR RURAL ENERGY
APPLICATION TO RUN A.C. AND D.C. LOADS” is successfully tested and
implemented which is the best economical, affordable energy solution to common people.
This can be used for many applications in rural areas where power availability is less or
totally absence. As India is a developing country where energy management is a big
challenge for huge population. By using this project we can drive both A.C. as well as D.C
loads according to the force we applied on the piezo electric sensor. Our prototype
demonstrates that a floor generator can be done
A DC generator can illustrate the concept, but the reliability and durability are questionable,
Newer technologies could make a very reliable generator
Proposal for the utilization of waste energy of foot power with human locomotion is very
much relevant and important for highly populated countries like India and China. The whole
human/ bio-energy being wasted if can be made possible for utilization , it will be great
invention and crowd energy farms will be very useful energy sources in crowded countries.
Some 28,527 steps, for example, could power an entire moving train for a second. The
Crowd Farm could also be used to harness the head-bashing energy at a rock concert. Nonconventional
energy system is very essential at this time to our nation.
