IOT APPLICATIONS FOR SMART
CITIES

INTRODUCTION
• Technology and mobile services have observed a giant leap in the past few
years.
• With improvement in these technologies people are getting ‘smarter’.
• This smartness is not just limited to people as technology has also inspired
these people to make their cities smart along with them.
• IoT is one such technology which is being used make changes in how cities
are managed and developed.
• It has inspired people to achieve better development goals such as
managing community services and achieve sustainability goals.

WHAT ARE SMART CITIES ?
• Cyber-physical environments with advanced
communication systems and infrastructure over
the city.
• They are built with an objective to optimize
sustainability and improve quality of life of the
citizens.
• City infrastructures such as healthcare systems,
road networks, waste management systems etc.
are improved in such a smart city environment.
• Smart building or environmental monitoring
systems are some applications which make such
a smart city [3].

APPLICATIONS: SMART HOMES
• With IoT services, they systems inside a
home or even a building can be
automated.
• Buildings use sensors and actuators to
make this possible.
• Processes such as heating, cooling, light
controls etc. can be monitored and
controlled.
• These services can also be implied to
fire alarm systems, water pumps, power
meters and other such areas.
• With the implementation of these
strategies, costs can be reduced in these
sectors and sustainability can be
achieved.
• Overall, the building operations can be
improved and time for decision-making
can be reduced.

APPLICATIONS: ENVIRONMENTAL MONITORING
• Heterogenous data from sensors can be
collected.
• The sensors can sense variations such as
wind, temperature difference,
precipitation probability, humidity
percentage etc.
• With this data, natural calamities can also
be detected.
• Knowing about calamities in advance can
help take preventive measures well in
advance.
• With these sensors, air quality can also be
monitored which can thus provide
information about carbon emission
percentage and measures can be taken to
reduce the carbon footprint accordingly.

PUBLIC TRANSPORT
• With IoT implemented in the public transportation systems, details about
the arrival and departure of trains and buses can be made available to the
people.
• This can help the passengers to plan their travel accordingly.
• Safety features can also be enhanced with such technology providing
information about when the parts of the vehicle need replacement or
provide necessary warnings.
• All such features would ensure an overall better commutation experience.

WASTE MANAGEMENT
• With Internet of Things, waste management services around the city can be
enhanced.
• Ultrasonic sensors are used to detect the level of waste in dumpsters.
• IR sensors filter the waste based on the moisture level, separating the waste
under wet & dry waste.
• Messages can be sent to the employees if a dumpster is full so they can start
their collection services accordingly.
• This can help better waste collection services all around the city ensuring it stays
clean.

SMART WATER FOR CITIES
• Data about water flow, availability,
pressure and distribution can be
monitored.
• This can help to manage water
supplies efficiently around the city.
• Water quality can also be kept in
check.
• Users can get details about their
usage of water if they have a smart
pump installed at their homes.
• Long term cost benefits can be
achieved along with sustainability.

TRAFFIC MANAGEMENT WITH IOT
• Traffic lights can use real time feeds to
control lights accordingly.
• This helps in diverting traffic to less
congested areas and keeping the traffic
under control.
• IoT based sensors can give details about
vacant parking spots to the public which
will help them to find parking spaces easily
and quickly.
• Cameras can help to detect major accident
spots and signs can be placed according to
that data.
• These cameras can also detect accidents
on their own and report them to the
nearest hospital automatically.

CONCLUSION
COST-
• The cost for implementation of this technology in the cities can
initially be high.
• The long term benefits provided with these services will be a trade-off.
BETTER QUALITY OF LIFE-
• With these services, the general public can observe a significant
improvement in the quality of their life as many general services are
available to them at their fingertips.
• Sustainable growth can be achieved.
• Energy consumptions can help reduce costs of living.
