FIELD OF THE INVENTION
As many smart appliances are now included in modern houses, energy management of these
gadgets has become crucial. In this research, a smart home distribution board based on the
Internet of Things was created to track the functioning of various appliances. Our project,
dubbed "An Autonomous Smart Distribution Board" represents a considerable improvement
over the conventional distribution board, adding an extra layer of security.
BACKGROUND OF THE INVENTION
As with conventional energy meters, users are unable to identify voltage and current
fluctuations in their appliances, which destroys the entire set of equipment and can occasionally
result in fatal accidents. So, our project is here to secure the switch boards which are facing
voltage fluctuations and short circuits in their lifetime which damages the electrical appliances
through which cost it directly associate.
The cost efficiency and safety of these systems our project help to overcome these major
problems by sending the user an alert notification just prior to the fluctuation in voltage which
can be happened by any technical glitch in the system after the installation of our device. This
gives the user a chance to avoid the damage which could happen by Flicker.
PRIOR ARTS AND THEIR DEMERITS
Due to the fact that users of traditional energy meters are unable to identify voltage and
current fluctuations in their appliances, the entire set of appliances is damaged, and in some
cases, tragic accidents occur.
OBJECT OF THE INVENTION
1. To distribute the users with an efficient amount of electricity.
2. In order to raise the appliances' power factor.
3. It will warn user through the IoT over the internet.
4. To protect the appliances from earthing as well as the short circuit protection of the wires.
In the current world where in almost all house switch boards are present which are used for
ease of living and usage of appliances. As the modern world is adapting new technology day
by day in every field this is no longer a field to get its own technological advancement. So, our
project is here to secure the switch boards which are facing voltage fluctuations and short
circuits in their lifetime which damages the electrical appliances through which cost it directly
associated, so for the cost efficiency and safety of these systems our project help to overcome
these major problems by sending the user an alert notification just prior to the fluctuation in
voltage which can be happened by any technical glitch in the system after the installation of
our device. This gives the user a chance to avoid the damage which could happen by Flicker.
SUMMARY OF INVENTION
The hardware created can track real-time voltage and current activity in the electric board as
well as track electricity usage based on IoT. Users may keep an eye on their appliances with
the help of this feature, which also raises consumer awareness of power usage. It serves as an
extra layer of defense for the equipment by early spotting weather and electric surges and
sending out alerts via handheld devices, lessening the risk of disaster. The entire process of
controlling voltage fluctuation, detecting power factor fluctuations, and consumption becomes
more intelligent and extremely efficient by integrating IoT components into the distribution
board. To achieve this, reliable mechanisms and autonomous judgments built on exact,
ongoing real-time monitoring of board current flow are developed. As a result, these smart
boards performance has greatly enhanced.

DESCRIPTION OF THE INVENTION
BLOCK DIAGRAM
Block diagram of the proposed project is shown in fig 10. Once the device gets on, the decisionmaking device (ESP8266) (2) sends signal to activate the LCD (3). The LCD will show the
passed reading of the Appliances (3). After this ESP8266 (2) will send signal then the relay (4)
will turn on and it will unblock the flow of supplied power, then the power will flow in the
RCCB (5) and then to the load (7). After the power supply is supplied to the load the PZEM004T (6) will sense the current and voltage fluctuation/readings of the load. This PZEM-004T
(6) will send the signals/data to ESP8266 (2). After this ESP8266 (2) will send the data to the
user over the internet using IoT and the user will respond to the data.
EXPERIMENTAL HARDWARE COMPONENT DESCRIPTION OF
THE PROPOSED DEVICE
The analysis and design of the smart energy distribution board is implemented in hardware.
The input power is taken from AC source and converted to 5V DC, which is the requirement
of the working of the microcontroller. The electronic components used in this project are as
follows:
1. PZEM-004T: - Voltage, current, power, and energy are four electrical variables that it
is capable of monitoring. Excellent for monitoring AC (RMS) voltage, current, and
power is the small PZEM-004T circuit (single-phase). Using the code library, the device
connects to Arduino and other electronics with ease.

2. ESP8266(Node MCU): - Using IEEE 802.11, the ESP8266 module allows
microcontrollers to connect to 2.4 GHz Wi-Fi. A self-contained SoC with an inbuilt
TCP/IP protocol stack that can provide access to your Wi-Fi network is the
ESP8266WiFi Module.
3. Switching Circuits: In this project switching circuit consists of Relay (4) and RCCB
(5).
a. Relay: We have used Relay as a switching circuit. It is an electronically
operated switch. When current flows through the coil, it generates a magnetic
field which attracts the lever and the changes the switching contact point.
Current can be made on and off using it. 5VDC 240VAC relay is used in this
project.
b. RCCB: When it comes to safeguarding electrical circuits, residual current
circuit breakers (RCCB) are a crucial safety precaution. It is a current detecting
device, and anytime a defect develops in the linked circuit or the current exceeds
the rated sensitivity, it may automatically measure and terminate the connection.

4. DS18B20 Temperature Sensor: - It is at temperature sensor. It is widely used to
measure temperature in hard environments like in chemical solutions, mines or soil etc.
It can measure a wide range of temperature from -55°C to +125° with a decent accuracy
of ±5°C. Each sensor has a unique address and requires only one pin of the MCU to
transfer data so it a very good choice for measuring temperature at multiple points
without compromising much of your digital pins on the microcontroller.
5. 1602 I2C Display: - This YELLOW Backlight 2 x 16-character LCD Module employs
an I2C interface to communicate with the host microcontroller. This budget-conscious
LCD is used on projects requiring the display of text, data, or ASCII
characters of all types.
6. SMPS 5V: - It is a power supply unit (PSU), and it is often used in computers to replace
the voltage to the appropriate range for the computer. An SMPS adjusts output voltage
and current between different electrical configurations by switching the basics of
typically lossless storage such as capacitors and inductors.
