Control System for Optoelectronic Complementary Intelligent Greenhouse

In order to achieve intelligent monitoring and efficient control management of agricultural greenhouses, this paper designs a photoelectric complementary intelligent greenhouse control system based on STM32 microcontroller. This system integrates multiple sensors to monitor crop growth environment data such as temperature, humidity, light, soil moisture and CO<inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf> concentration. inside the greenhouse. At the same time, by connecting the Wi-Fi module to the mobile app, users can remotely monitor various environmental parameters inside the greenhouse and take remote visualization operations to maintain the crop growth environment in the most suitable range. The monitor can provide real-time feedback on the environmental status inside the greenhouse. When the environmental parameters are not within the range set by the system, an audible and visual alarm will be triggered. Through the control system, functions such as ventilation, irrigation, supplementary lighting, shading, humidification, dehumidification, heating and cooling can be achieved in the greenhouse. This design also adopts a diversified and effective supply of energy through photovoltaic complementarity. This system can provide the most suitable growth environment for crops and efficiently achieve intelligent control and management of greenhouses.
