This paper presents the design and development of a energy metering device that can be used for monitoring, recording energy consumption by various home appliances.The device uses Node MCU ESP 32 as the central controller and a voltage sensor - ZMPT101B as well as a current sensor - ACS712 as its major components. Besides these, for displaying the voltage and current consumption and other parameters an 128*64 OLED screen is used. Also the device is interfaced with the IoT based Blynk mobile application. This facilitates transmission of the sensor data to Blynk cloud storage through ESP32 Wifi module. Real time monitioring of energy consumption thus becomes possible. The device is tested to measure power consumption by AC as well DC loads. The real time measurement readings can also be shared to other devices over the internet. The design provides an efficient means to monitor the energy consumption by AC and DC powered appliances.
