The problem SMART ENERGY METER FOR DOMESTIC PURPOSE solves

The conservation of energy is very much need in this modern world. It is very important for our future generation too. This project allows us to be conscious about the future and save power for further use.Similar projects like this usually use internet connection for transmission of data. The main advantage of our project is that we can see the data from the sensor without the use of internet connection. The budget is also low compared to other existing models. The usage of Node-MCU allows us to operate the Power meter even without the use of internet. Node-MCU connects through the local network which includes a Wi-Fi modem, mobile phone.NodeMCU is an open source IoT platform based on ESP8266 which can connect objects and let data transfer using the Wi-Fi protocol.
PZEM-004T is an electronic module that functions to measure: Voltage, Current, Power, Frequency, Energy and Power Factors
The Node-MCU is connected to PZEM sensor which calculates the units of power used and Relay controls the MCB. We set the limit of power consumed and if it reached the limit the relays turns on and switches the MCB off to stop the power supply. Relay will turn the MCB off when it detects that the supply and return current are not balanced.
The load wire is inserted inside the PZEM sensor which calculates the power used displays it in LCD. We can see the power consumed by using the HTML page, by copying the IP address and pasting it in the chrome browser. A static IP address is created for this. It displays the power consumed, current, and voltage etc., used. By using the mobile phone we can see the amount of power consumed in our home or work place and conserve the electricity accordingly.

Challenges we ran into

1)creating a static IP address
