Abstract：An intelligent management system for strawberry greenhouses based on ESP32 and the MQTT protocol was studied.The aim is to automatically adjust heating,cooling,alarms,and fan switches by collecting parameters such as temperature,humidity,light intensity,carbon dioxide concentration,and soil temperature and humidity within the strawberry greenhouse,thereby providing an optimal growing environment for strawberries.In terms of research methods,on the hardware side,ESP32 is selected as the main control chip,combined with temperature and humidity sensors,light sensors,carbon dioxide sensors,and soil temperature and humidity sensors to obtain environmental data.A fan is used to simulate heating and cooling devices,and a buzzer is used to implement the alarm function.In terms of software,programs are written using the Arduino IDE to control ESP32 to read sensor data and send the data to the ThingsCloud cloud platform for storage and processing via the MQTT protocol.The innovation of this system lies in its ability to intelligently monitor and manage the strawberry greenhouse environment,automatically adjusting device states based on real-time data.The results show that the system can accurately monitor the environmental parameters inside the greenhouse and automatically execute operations such as heating,cooling,alarming,and fan switching,effectively improving the yield and quality of strawberries.Through testing and verification,the system is proven to be stable in performance and has achieved the expected goals.
