Imagine if we want to alert or notify someone in by ringing bell remotely through your smartphone. This project was taken consideration for such cause. Upgrade our custom automated School Bell with emerging concept of IOT (Internet of thing) where the entire process of ringing bell is automated and integrated with internet and can set alarm or ring alarm in case of emergency remotely through a smartphone. Highly encrypted with support of Firebase server.

3. The ringing of a school bell is a signal that tells a school's students
when it is time to go to class in the morning or afternoon and when it is time to change classes during the
day as well as when students are dismissed from school.
In some schools it may take the form of
a physical bell, usually electrically operated. In other schools it may be a tone,
siren, electronic bell sound, a series of chimes, or music played over
an intercom.
Introduction
Hence in both case it requires the waste of time to operate.
So the thing we made through this project is we automated the process of
Alarming as a part of IOT.

10. It gives a complete solution for the authentication problems (login issues) , apart from
authentication it also provides a solid solution for the database problems , it gives us a real
time data base ,real time in the sense as soon as the user writes a code , the database entry
is done at instant which will be very useful for debugging . which will be only
done using a firebase .
These authentication and database acquisition are the ground application of the firebase , but
it can lot of other things such cloud messaging and app notification etc

13. NodeMCU is an open source IoT platform.It consists of
firmware which runs on the ESP8266 Wi-Fi SoC It includes
hardware which is based on the ESP-12 module. Internet of
Things (IoT) is a network of several devices embedded with
Electronics, Software and Sensors used for connecting and
exchanging data among the devices

15. Uses of relay in our project
•It is used for safety purpose in the circuit.
•When there is excess flow of current in the circuit, then the relay coil opens and the
flow of current to the circuit interrupt in the circuit untill the flow of current becomes
normal.
Specifications of relay used in our project
•Range-12v
•Type-two phase relay

16. The clock connection of this chip to Arduino is simple. It is as
follows. We need four wires, for powering the module Vcc and
Gnd pins Is connected and the 2 i2c communication pins SDA
and SCL.
• Vcc is the supply (3v to 5v supply)
• Gnd is ground
• SDA is Serial data
• SDL is serial clock

18. While using the school bell ringer we have sufficient time for the major responsibilities
expected of teachers and highly benefitted to the students
 CLASSROOM MANAGEMENT: Designing a real world learning experiences and motivating a
diverse group of learners .
 TIMINGS: There is no delay in timings .Hence, the students will enter the class immediately.
Bell ringing limited to the duration of time periods, intervals, lunch time.
 EMERGENCY SIGNALS: This can be used in emergency purpose. once there is an urgency of
bell ringing the setting can be reframed on the accomplish of the user or administrator.
 It can be also used in offline mode also without the use of connecting devices.
 Cost efficient and highly beneficial one in today's world.
 While using this we can save the efficient time of manual user and time delay will be reduced.

23. Finally I would to conclude my report while illustrating the feautures
 It can be also used in offline mode also without the use of connecting devices.
 Cost efficient and highly beneficial one in today's world.
 While using this we can save the efficient time of manual user and time delay will be reduced.
Hence, engineering is all about innovation and adapting to new about innovation and adapting to
new technologies we as a team of future engineers had really worked hard for this project both our hardware and
software team has given our best for the successfull out come of this project. We hope that each sound from this
bell will always portray the pride of our electrical and electronics engineering department.we would like to thank
RAMKUMAR sir and KHAN sir for guiding us even when our path was full of obstacles And Foremost I would like to
thank Almighty for providing enough patience to accomplish my project.24-05-2020 ©nsmd 23
