IOT based Smart energy metering system

computer science and engg

Today technology has changed across the world in a way human interact with the physical world. Internet of Things has paved the way for us allowing us to insert technology into day to day physical objects. In this paper an Energy Meter with Smart Monitoring of Home Appliances based on the Internet of Things is built. This paper proposes a system which eliminates manpower by self-regulating meter readings and bill generation reducing the flaws which are one of the major cause for energy-related corruption. The demand for transparency in the domain of energy estimation has emerged as there isn't a verification facility. Node MCU is used as the central controlling unit in this system. For energy meter, the ZMPT101B voltage sensor and ACS712 current sensor are interfaced with a microcontroller. The readings of voltage, current, the power consumed, no. of units and the corresponding price are calculated and are displayed over the 16*2 LCD Display module. An Infra-red based flame sensor is used as a fire safety measure. Monitoring of home appliances is done by using an 8 channel relay module to which loads are connected and operated over voice commands using Google Assistant with IFTTT (If this then that) platform which is interfaced with IoT based Blynk app on mobile. A DHT11 sensor is used for monitoring the temperature and humidity inside the house. All the readings obtained from the sensor is sent over the GSM module to Blynk platform
