Contents I. Introduction
In August 2021, the Sixth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC) declared that "it is unequivocal that human influence has warmed the atmosphere, ocean, and land." Furthermore, "man-made climate change is already affecting many weather and climate extremes in every region across the globe," according to the paper. It is anticipated that greenhouses will be even more impacted by climate change in the future. For instance, certain coastal greenhouses may be submerged due to rising sea levels. Furthermore, increasing the frequency of extreme weather events may increase the difficulty and cost of greenhouse operations. For a considerable amount of time, greenhouse agriculture has been a mainstay of the world's food production, making fresh produce readily available all year round. However, there are significant issues with crop monitoring, climatic management, and resource efficiency with standard greenhouse systems. A greenhouse, often referred to as a greenhouse system, is a specially constructed building that, regardless of the external weather, offers the ideal conditions for plant growth. Even under less-than-perfect circumstances, greenhouses provide an ideal environment for plant cultivation thanks to their exact control over temperature, humidity, and light. Essentially, by enabling farmers to produce fresh, healthy crops all year round without being dependent on the vagaries of the outside weather, greenhouses have transformed farming. That is the benefit and power of greenhouses. The control of critical environmental factors in a greenhouse, including temperature, humidity, light levels, soil moisture content, and carbon dioxide levels, is greatly aided by IoT devices. These gadgets collect useful information that may be utilized to reduce energy usage and maximize plant development. IoT can automate functions in a smart solar-powered greenhouse, like vent operation, shading curtain adjustment, and irrigation system activation, in addition to monitoring and managing environmental variables. This IoT technology will be improved by adding the optimal growth environment, which ultimately leads to connected victories. The principal aim of this study is to provide a comprehensive assessment of the current research status in the field of smart solar-powered greenhouses.
