Today's world is evolving toward creating a smart house where a multitude of Internet Of Things (IoT) devices and sensors are interacting to deliver plenty of useful information. Essential to the implementation of this IoT is the design of energy-efficient solutions aiming toward a low-carbon-emission, namely green, society. Many R\&D studies are working on a long-range distance wireless charging that will send microwave energy to powered IoT devices wherever it is in the room and without cords. Wireless power transmission technology is the diffusion of RF power without using any physical support. The vision of future technology is to make the IoT devices charging and powered wirelessly. The objective of the work scope is to combine the wireless power technology with smart IoT and IIoT devices and reduce the turnoff of devices due to battery depletion. In this research paper, we designed and realized a wireless charging device using the fundamentals of microwave radiation. The proposed electronic device takes all parameters above to deliver sufficient energy to charging any IoT devices wirelessly with a maximum power of 5W.
