Energy saving is the most important and challenging issue. Smart power meter is used in domestic electric power distribution system. The integration of the Node-MCU,PZEM sensor, Relay and provides the system as Smart Power Monitoring system. Smart power meter provides data for optimization and reduce the power consumption. This system communicates with embedded controller and ESP8266 module to transmit the data. Domestic consumers get benefited through this system.

Components Used
ESP8266 WiFi Module ESP8266 is a system on chip (SoC) which provides WIFI capability for embedded applications. This enables internet connectivity to embedded applications. ESP8266 modules are mostly used in Internet of Things(IoT) applications.	X 1

Description

HOW I BUILT MY PROJECT and WORKING:

The Node-MCU(Controller) 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.
