摘要
为保证教室内环境质量稳定在合理范围内,设计了一种智能教室环境监控系统。以STM32单片机为控制核心,与MG811型二氧化碳传感器,DHT21温湿度传感器,BH1750FVI光照传感器以及高精度的甲醛、PM2.5传感器等检测装置的配套,可完成对教室内环境状况的检测。以红外遥控模块为核心,通过单片机发送红外遥控编码实现空调的控制。SIM900通信模块向数据库发送数据,连接数据库的监控平台采用PHP语言进行开发,为管理者提供直观的监测控制平台。经过测试和试用,系统实现了对教室环境的实时监测,通过远程控制空调来调节室内温度。在某学校安装使用,达到了预期效果,满足设计要求。
In order to ensure the stability of the of a smart classroom environment monitoring system classroom environment within a reasonable range, the design With the STM32 microcontroller as the control core, with the MG811 type carbon dioxide sensor, DHT21 temperature and humidity sensor, BH1750FVI light sensor and high precision formaldehyde, PM2.5 sensor and other detection devices supporting the completion of the classroom environment to detect the situation. To infrared remote control module as the core, through the single-chip infrared remote control coding to achieve air-conditioning control. SIM900 communication module to send data to the database, connected to the database monitoring platform using PHP language for the development of intuitive monitoring and control platform for managers. After testing and trial, the system realizes real-time monitoring of the classroom environment, through the remote control of air conditioning to adjust the indoor temperature. Installed in a school to use, to achieve the desired results to meet the design requirements.
