By 2050, there will be 20 billion people on the planet, and it is predicted that they will use 71% more natural resources, which will increase power consumption and make sustainable development more difficult. Smart cities will therefore be required to address these issues and foster economic development. Although there are many various energy sources, including thermal energy, wind, solar, and tidal energy, that can be utilized to generate electricity, the current generation has trouble lowering the quantity of power used. An efficient solution that seeks to maximize the use of energy resources and has objectives for sustainable energy is provided by smart cities (renewable energy and energy-efficient technologies). This paper demonstrates the implementation of a smart city through the Internet of Things using the Node-MCU device. The major objective of this project's goal is to improve living standards by developing smart home automation systems, smart street light controllers, and smart irrigation systems that conserve water. People's quality of life is improved as a result of the smart city deployment utilizing Node-MCU because it enhances the economic infrastructure in a way that is both cost-effective and produces successful smart outcomes.
