The quantity and quality of crop yields determine the growth of the agriculture sector. By offering a regulated environment, polyhouse farming is a successful technique that optimizes yield with the least amount of resources. In order to improve farming precision, this paper suggests an automated smart polyhouse robotic system based on the Internet of Things. The system uses sensors and Internet of Things devices to continuously monitor and analyze conditions in order to increase crop yield and quality by automating tasks within the polyhouse. We suggested an automated method for determining crop- specific water and soil moisture levels. It removes the need for manual surveys by informing farmers about temperature, humidity, and soil conditions. A database containing the best crop management schedules is part of this system, which guarantees resource efficiency and boosts crop yield.
