4. Introduction
 An electricity meter or energy meter is a device that measures the
amount of electric energy consumed by a consumer.
 But sometimes the limited functionality of these meters. A possible
solution is a Smart Energy Meter (SEM).
 This measurement system is aimed to be used in measuring energy
related quantities such as units consumed, consumed power, active
load etc. of a house.

5. Objectives
The main objective of this project is to design and implement
an Android App (Electro Saving) to be used for an efficient
smart distribution load metering/monitoring system for both
consumer and provider perspectives. The main objectives
are:
 Consumer justified billing
 Real-Time monitoring & Control of electrical power
consumption
 Dynamic charges of tariffs

Calculations
 Voltage Measurement
Voltage is measured by the help of a voltage divider circuit. As the ARDUINO analog pin input
voltage is restricted to 5V I designed the voltage divider in such a way that the output voltage from it
should be less than 5V.
Vout=R2/(R1+R2)*Vin
Vin =230V
R1=500 and R2=10
Vout =10/(500+10)*230=4.5V
which is lower than 5v and suitable for ARDUINO analog pin.

 Current Measurement
For current measurement I used a ZMCT103C AC current transformer. According to AC current,
voltage is induced on both sides of IC.
Primary peak-current = RMS current × √2
= 100 A × 1.414 = 141.4A
Secondary peak-current = Primary peak-current / no. of turns
= 141.4 A / 2000
= 0.0707A
Burden resistance = (AREF/2) / Secondary peak-current
= 2.5 V / 0.0707 A = 35.4 Ω

Analog to digital conversions are dependent on the system voltage. Because we predominantly use the
10-bit ADC of the Arduino on a 5V system, we can simplify this equation slightly
If the analog voltage is 2.12V what will the ADC report as a value?
AEDUINO ADC convert Analog signal to corresponding digital approximation. The ADC reports
a ratiometric value. This means that the ADC assumes 5V is 1023 and anything less than 5V will be a ratio
between 5V and 1023.

12. Continue…
 Power Factor Measurement
This difference signal can then be timed by a microcontroller and
converted to power factor using the following calculation:
cos(phi) = f * dt * 360
Where, cos(phi) - the power factor, f - The frequency of the
measured supply, dt - delta t or time difference between the waves.

13. Continue…
 Power Measurement
Power is product of voltage (volt) and current (Amp)
P=V x I x cos(phi)
Unit of power is Watt or KW.
 Energy Measurement
Energy is product of power (watt) and time (Hour)
E= P x t
Unit of Energy is Watt Hour or Kilowatt Hour (kWh)

14. Hardware Specifications
The final product will be an integrated system based on hardware and software.
 The Hardware consist of ESP8266-12E, Relays, Arduino Uno Circuit, Voltage Transformer, Current
Transformer and DC Power Supply.
 The Android application (Electro Saver) will be available at the Android Play store from where
consumers and providers can download the app for free.
