摘 要
新会小青柑作为“茶届新宠”，其存储环境却较为苛刻，温度和湿度达到最适宜的条件下，才能使其存储时间到达最大化，其价值也可以达到最大化。若温度和湿度不适宜，新会小青柑可能会变味、发霉或者长虫。因此，为了使新会小青柑能够存储更长时间，设计一款新会小青柑存储环境智能监控系统很有必要，不仅可以延长新会小青柑的存储时间，还能减少人为操作。
本文提供了一个新会小青柑存储环境智能监控系统。它是用STM32为基础对电路进行控制的物联网系统。STM32可以通过温湿度传感器采集环境中的温湿度数据，再通过数据分析是否要采取措施去平衡环境，到达所要的环境需求。同时，温度和湿度的数据可通过无线模块传输到另外一块微控制器上，第二块微控制器可将得到的数据显示在显示模块上。还可以通过WIFI模块将数据上传至云平台。本系统的硬件部分组成有：DHT11传感器、CC2530串口收发模块、OLED液晶屏模块等。这个系统除了可以检测环境的温度和湿度，最大的特点是可以通过无线传输的方式，可以实现让用户实时地查看新会小青柑所处环境的温度和湿度，确保新会小青柑能够顺利保存。
通过设计与调试，本系统可以实现对环境的温度和湿度采集，然后通CC2530无线串口收发模块传输至第二个STM32单片机上，此时第二个STM32单片机的OLED显示屏模块可以显示温度和湿度的数据，还可以从云平台上观察温湿度数据。当温度和湿度大于设定的阈值时，系统会采取相应的措施去改善环境。该系统反应迅速，经济成本低，占地面积小，能量消耗少。

Abstract
As the "new favorite tea", the storage environment of Xinhui Xiaoqinggan is rather harsh, and the temperature and humidity can reach the most suitable conditions to maximize the storage time and its value. If the temperature and humidity are not suitable, Xinhui Xiaoqinggan may become tasteless, moldy or long insects. Therefore, it is necessary to design an intelligent monitoring system for the storage environment of Xinhui Xiaoqinggan in order to store it for a longer time, not only can it extend the storage time of Xinhui small green oranges, but also reduce human operations.
This paper provides an intelligent monitoring system for the storage environment of Xinhui Xiaoqingkang. It is an IoT system using STM32 as the basis for the control of the circuit. STM32 can collect the temperature and humidity data in the environment through temperature and humidity sensors, and then analyze whether to take measures to balance the environment and reach the desired environmental requirements through the data. Meanwhile, the temperature and humidity data can be transmitted to another microcontroller through a wireless module, and the second microcontroller can display the obtained data on the display module. The data can also be uploaded to the cloud platform through the WIFI module. The hardware part of this system consists of DHT11 digital temperature and humidity sensor, CC2530 wireless serial transceiver module, OLED LCD module, etc. Besides detecting the temperature and humidity of the environment, the biggest feature of this system is that it can be transmitted wirelessly, which can realize to let users check the temperature and humidity of the environment where Xinhui Xiaoqingkang is located in real time and ensure Xinhui Xiaoqingkang can be preserved smoothly.
Translated with www.DeepL.com/Translator (free version)Through design and debugging, the system can achieve temperature and humidity acquisition of the environment, and then through the CC2530 wireless serial port transceiver module transmitted to the second STM32 microcontroller, at this time the second STM32 microcontroller OLED display module can display temperature and humidity data. When the temperature and humidity are greater than the set thresholds, the system takes appropriate action to improve the environment. The system responds quickly, has low economic cost, small footprint and less energy consumption, which can solve the problem of Xinhui small green orange storage and reduce the cost of merchants.
