In recent years, Internet?of Things (IoT) has been widely applied in greenhouse control to realize intelligent automation and data-driven greenhouses. In IoT based greenhouse, the real time status of soil moisture content, air temperature & humidity and CO2 concentration is monitored and controlled using embedded system technologies (Arduino or?Raspberry Pi) and wireless communication modules. Sensors, wireless technology and data analytics can be combined for real-time monitoring and marching orders so that the optimal conditions are met for growth and crop?yield. Moreover, the use of artificial intelligence (AI) techniques (fuzzy logic, machine learning and bio-inspired algorithms) increases the?flexibility of the platform, the ability of prediction and decision-making performance. These smart systems eliminate manual labour, process costs?and resource waste with eco-friendly.
