3. 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.

4. 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 ·

8. Mathematical Modelling & 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. V out =R2/(R1+R2)*V in V in =230V R1=500 and R2=10 V out =10/(500+10)*230= 4.5V which is lower than 5v and suitable for ARDUINO analog pin.

9. Continue… Current Measurement For current measurement I used a ZMCT103C AC current transformer . A ccording 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

10. Continue…. 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.

11. 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.

12. 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)

13. 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.

14. Continue… ESP8266 -12E WI-FI Module ESP8266-12E is a low-cost IoT platform with integrated TCP/IP protocol stack and 32-bit low-power central processing unit (CPU). ESP8266 can be easily programmed to allow data exchange between Arduino and Firebase cloud.

15. ESP8266 Interfacing with Arduino

16. Continue… Voltage Sensor T he voltage transformer ZMPT101B are used due to their compatible ready-made modules/shields that can be easily deployed with the Arduino Uno. Interfacing a voltage sensor with Arduino or any other microcontroller is pretty straight forward.

17. Interfacing a voltage sensor with Arduino

18. Continue… Current Sensor T he Current transformer ZMCT103C are used due to their compatible ready-made modules. The module can measure within 10A current and it can transform 10A input to 10mA output.

19. Interfacing a Current sensor with Arduino

20. Continue… Liquid Crystal Display (LCD) 2004A LCD Display Board is a 20x04 character in 4 rows, high quality, blue/green backlight, and white character display . The model name of 2004 means 20 columns (characters) multiply 04 rows, so this display can show  20 characters in each of the 4 rows of the 2004 LCD . The module can easily be interfaced and communicated to an Arduino board. 

21. Interfacing a LCD Display with Arduino

22. Continue… Switching Relays The switching relay controls energy consumption either manually by using Arduino sketches or remotely by the user through a mobile application.

23. Interfacing a Relay Board with Arduino

24. Continue… Arduino Uno Arduino board is the heart of our system. Entire functioning of system depends on this board. Arduino reacts to the 5v supply. We chouse this due to its simple programming with Arduino compiler, easy start‐up, user‐friendly, and available peripheral libraries.
