This paper presents the design and implementation of an IoT-based smart home intelligent system for monitoring the electrical energy consumption based upon the real time tracking of the devices at home. The proposed outcome of this paper aims at multiple benefits of saving on electricity bills of the home as well as keeps the users updated about their home security with an option of controlling the switching of the devices by using their simple toggle touch. Finally, this paper reduces electrical energy consumption. Smart home environments integrate multiple IoT devices and services that collect method and exchange information. They supply users many prospects to manage and adapt the standing of their home manually. For the detection of the human, PIR Sensor is used and for the security purpose, Gas Sensor is used in this paper. The main purpose of the Gas sensor is to detect the strong smells such as LPG, Hydrogen, Propane, Smoke, etc. In this model we have proposed an Ethernet based system that let users monitor real time switching information of the electrical devices and controlling them through an webpage as well as monitoring the security of their homes in case of unwanted entry . Our model uses gas sensor to check for gas leak at the users home, PIR motion sensors to check for the unwanted presence at their homes and also monitor and control the real time tracking and switching of all their electrical devices through an webpage. © 2018 IAEME Publication.
