One of today's most important technologies in the world is the Internet of Things (IoT). It is a technology that is important in many fields and is rapidly advancing. The current study has critically evaluated IoT from the dawn of technology to the present. According to the study's conclusions, the IoT has several uses in a range of industries, including the development of urban communities, the coordination of required frameworks and resources, flexibility, transportation, and collaborations. This technique operates by using a variety of sensors. IoT is expanding daily as a result of the creation of numerous sensors that can detect a variety of climatic conditions. IoT development has shown that more organised data is being evaluated, protected, and transferred in a number of situations.
