This is the circuit connections which i have followed for this project.
Aim - To setup a simple websocket connections with ESP3266.
Aim - To calibrate and get accurate readings from Voltage sensor
Voltage sensor calibrated and displayed on the serial monitor

Video I referred to
Aim - To enclose all the sensors and the circuit within a box and integrate the voltage sensor code with the main code
- The smart plug can remotely switch on and off any appliance which is connected to it.
- It can also measure the voltage(Vrms).
- The current value is fixed to 2.0 Amps(next step is to integrate the current sensor)
- Both power an energy calculation is done successfully and displayed on the Blynk app as well as the terminal.
Code used
Aim - To integrate the current sensor so that we can accurately determine the power consumed.
Current sensor which we are using is SCT013
Aim - To integrate wifi manager which prevents from hardcoding wifi credentials.
