    Fig.1 Smart energy meter

    Energy meter used here is clamp energy meter .230V AC mains is the input given to the transformer and AC mains is converted to low voltage.

    Energy meter measures the live current, voltage and power in terms of KW-h. Microcontroller reads these parameters and send it to the cloud. NodeMCU is a Wi-Fi device which has a microcontroller in it. This connects the local router through IoT. The status of these parameters can be obtained through mobile or laptop.

    WIFI is used for data communication. WIFI is configured with Arduino.

    The Data from the Energy meter is sent to Arduino and to WIFI module and it reaches the users mobile phone. In this system the user can switch on/off the mains or home appliances from their Android smart phone app. The WIFI module trans and receives the data from cloud and sends to Arduino and the Arduino controls the relay to switch on and off the circuit of the home [8-9].

    1. Transformer

      Selecting a suitable transformer is of great importance. The current rating and the secondary voltage of transformer is a key factor. The current rating of the Transformer depends on the current needed for the load to be driven. The input voltage to the 7805 IC should be at least 2 volt greater than the required 2 volt output; therefore it requires an input voltage at least close to 7V. So, a 6-0-6V transformer with current rating of 500mA is use.
