For many years, automation has advanced significantly worldwide. Agriculture is one field where automation is used extensively. Farmers in rural areas will benefit from greenhouse technology, which replaces human direct supervision with automatic monitoring and control of the greenhouse environment. The generic architecture that can be used for many other automation applications is the paper's main focus. Crop growth is essential given technological advancements. A greenhouse is a climate-controlled building with walls, roofing, and other design features for off-season plant growth. One of the most recent developments in information and communication technology is the internet of things, which enables worldwide connectivity and information management for users and sensor devices. In order to ensure that the crops have the best possible circumstances for growth and yield, temperature/humidity sensors, moisture sensors, and light sensors are used effectively inside the greenhouse to activate cooling fans, LED lights, and motors, respectively.
