The problem IOT BASED POWER
MONITORING SYSTEM solves,
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.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

*) 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.
