IoT Based Smart Home Automation using Wireless Power Transfer

Access to power is a prerequisite for the efficient operation of any electrical / electronic circuit. The power transmission channel can be either physical (wires, cables, etc.) or non- physical (i.e. wireless). Wireless power transmission is a broad term used to describe any method used to transmit energy to electrical-based systems and devices. Wireless power transmission is one of the modern approaches in the field of electrical engineering. With the increasing demand for electronic devices, the need for their charging equipment has also increased. In this paper, a wireless power transmission system is developed to provide an alternative to the use of power cords for electrical /electronic devices. With this technology, challenges such as damaged or tangled power wires, spark hazards and extensive use of the plastic and copper used in wire production are solved, and the need for batteries in non-portable devices is eliminated. Moreover, an inductive coupling method for wireless power transmission system is developed through IoT (internet of things) data sharing at the web domain through the internet. In the perspective of IoT, an additional part of home automation is added with this work so that we can control any type of load (lighting, entertainment system, and appliances, home security) remotely via the internet. If we want to charge a battery, the device system will show the status of all the parameters of battery (charging status, battery status, voltage, current, humidity, temperature) via the internet. The performance achieved is a good indication that power can still be transferred across a medium range. In addition, possible approaches to improve the system's efficiency are discussed.
