摘要
随着社会对出入口管理安全性与便捷性要求的不断提高，传统门禁系统依赖实体钥匙或刷卡的方式，存在易丢失、易复制、接触传播风险等问题，难以满足现代智能化、卫生化管理的需求。
基于 STM32F103C8T6 单片机的非接触手势识别门禁，整合了 PAJ7620 手势模块、DS1302 时钟模块、CN-TTS 语音播报模块、SU-03T 语音识别模块、OLED 显示屏、WiFi 模块 ESP8266 及门锁执行机构，实现了门禁的非接触式智能控制与管理。系统核心功能包括：通过 PAJ7620 手势模块识别手势，在设定开门时间范围内，检测到从左往右手势时控制门锁打开，从右往左手势时控制门锁关闭；借助 DS1302 时钟模块获取当前时间，OLED 显示屏实时显示时间及锁的开关状态；当检测到正确手势且门打开时，CN-TTS 播报 “开门成功”，手势不正确时播报 “指令错误”；通过 SU-03T 语音识别模块，CN-TTS 可播报当前的年月日时分秒；利用 WiFi 模块将门的开关状态同步至手机端，支持远程控制门的打开，以及远程修正当前时间、设置开关时间范围，不在规定时间范围内时，无法通过手势打开门。
该系统的实现，有效提升了门禁管理的智能化与便捷性，避免了接触式操作带来的卫生隐患，确保了出入口控制的安全性与灵活性，为家庭、办公场所等场景提供了高效、卫生的门禁解决方案，同时为同类非接触式门禁设备的研发提供了参考，具有较高的实际应用价值。

ABSTRACT
With the rapid development of modern agriculture, precise regulation of greenhouse environments is of great significance for improving crop yield and enhancing agricultural product quality. Traditional manual management methods not only rely on empirical judgment with delayed responses but also suffer from high labor intensity and inconsistent parameter control, making them difficult to meet the needs of large-scale and intelligent cultivation.
The greenhouse environment measurement and control system based on the STM32F103C8T6 microcontroller integrates hardware such as DHT11 temperature and humidity sensors, MH-Z19 carbon dioxide sensors, FC-28 soil moisture sensors, 5516 light detection modules, RTC clock modules, buttons, OLED displays, ECB02 Bluetooth modules, and executive devices (ventilation devices, heating devices, cooling devices, irrigation equipment, supplementary lighting equipment, etc.), realizing automatic monitoring and intelligent regulation of the greenhouse environment. The core functions of the system include: real-time monitoring of temperature and humidity through DHT11, activating ventilation or cooling devices when the temperature is too high, triggering heating when the temperature is too low, and linking irrigation equipment to increase humidity when the humidity is too low; detecting carbon dioxide concentration through MH-Z19, starting fertilization devices when it is below the threshold, and activating ventilation when it is too high; synchronizing time with the internal RTC and setting supplementary lighting periods, and combining with the light detection module to automatically supplement light when the light value is lower than the threshold and within the supplementary lighting period; detecting soil moisture through FC-28 and controlling irrigation equipment to water when it is below the threshold; supporting time correction, setting of various parameter thresholds through buttons, as well as manual control of ventilation, heating, cooling, irrigation, supplementary lighting, and mode switching; real-time display of various monitoring data and equipment status through the OLED display; synchronizing data to the mobile phone via the Bluetooth module to achieve remote monitoring and equipment control (ventilation, heating, cooling, irrigation, supplementary lighting, and mode switching).
The implementation of this system effectively improves the automation and intelligence level of greenhouse environment regulation, reduces manual intervention, ensures the stability and accuracy of environmental parameters, provides an efficient and reliable solution for large-scale crop cultivation, and also offers a reference for the research and development of similar agricultural environment measurement and control equipment, with high practical application value.
