Intelligent contactless IoT timer control system for electrical socket using wireless interface

Abstract

The conservation of energy is a significant problem that permeates every aspect of modern life. Over the course of the last few
decades, there has been an increase in the rate of power consumption as well as the costs associated with it. This growth is often
the consequence of excessively leaving electrical equipment on, even when they are not being used in the most effective manner.
Having the capacity to remotely turn on or off a socket or to remotely establish a time restriction for how long an appliance may be
powered on can both contribute to the reduction of energy use. This paper presents an internet of things (IoT) based timer controlled
electrical socket system that uses micro-controller and relays to automatically control the usage of electrical appliances. The system features an IoT remote controlled device that can be programmed to control the power outlet’s configuration, as well as real-time monitoring of the sockets status (either ON or OFF). This system can also be used to prevent overconsumption of energy and minimize the risk of electrical fires and accidental electrocutions. The system is developed with a wireless control web interface to enable the remote access to the controlled sockets. On evaluation, the proposed system presents an advantage to enhance energy usage and conservation.
