摘要
随着现代化农业的快速发展，对农业生产环境的精准监测与管理成为提升作物产量和品质的关键。传统农业生产中，依赖人工巡检的环境监测方式存在效率低下、数据滞后、管理成本高等问题，难以适应规模化、智能化农业的发展需求。
基于 STM32F103C8T6 单片机的智能农业检测系统，整合了 YL69 土壤湿度传感器、5516 光照检测模块、DHT11 温湿度传感器、OLED 显示屏、按键及 ESP8266 WiFi 模块，实现了农业生产环境的自动化监测与数据远程传输。系统核心功能包括：通过 DHT11 实时采集环境温湿度，为作物生长环境评估提供基础数据；借助 YL69 土壤湿度传感器监测土壤水分状况，直观反映作物生长的水分条件；利用 5516 光照检测模块获取光照强度信息，为作物光合作用评估提供依据；通过 OLED 显示屏实时展示各项监测数据，方便现场管理人员直观掌握环境状况；依托 ESP8266 WiFi 模块将采集的温湿度、土壤湿度、光照强度等数据传输至手机端，实现远程数据监测与查看。
该系统的实现，有效提升了农业环境监测的自动化水平，减少了人工巡检的劳动强度，确保了监测数据的实时性与准确性，为农业生产的精准管理提供了数据支持，同时为同类智能农业检测系统的研发提供了参考，具有较高的实际应用价值。

ABSTRACT
With the rapid development of modern agriculture, real-time and accurate monitoring of agricultural environmental parameters is crucial for improving crop yield and quality. Traditional manual detection methods are not only inefficient and lagging in data feedback but also have problems such as high labor intensity and difficulty in centralized management, which cannot meet the needs of modern agricultural informatization and precision farming.
The intelligent agricultural detection system based on WiFi technology, with STM32F103C8T6 microcontroller as the core, integrates YL69 soil moisture sensor, 5516 light detection module, DHT11 temperature and humidity sensor, OLED display module, and ESP8266 WiFi module, realizing comprehensive monitoring and data transmission of agricultural environment. The core functions of the system include: real-time detection of soil moisture by YL69 to grasp the water demand of crops; monitoring of ambient light intensity by 5516 to provide a basis for light supplement management; real-time acquisition of temperature and humidity data by DHT11 to reflect the microclimate of the growing environment; real-time display of all detection data (soil moisture, light intensity, temperature, humidity) through OLED display module for on-site viewing by managers; wireless transmission of collected environmental parameters to the mobile phone terminal through ESP8266 WiFi module, enabling remote real-time viewing of data and understanding of crop growth environment dynamics.
The implementation of this system effectively improves the real-time and accuracy of agricultural environmental monitoring, reduces the labor cost of manual inspection, and provides data support for scientific farming. It realizes the integration of on-site monitoring and remote data transmission, which is conducive to the centralized management of agricultural production. At the same time, it provides a feasible solution for the development of intelligent agricultural detection equipment and has important practical value for promoting the informatization and intelligent transformation of agricultural production.
