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.
