二、项目简介
1.功能详解
基于STM32的档案室环境监测系统(机智云版)
功能如下：
- 温湿度采集：系统通过DHT11模块采集温湿度
- 光敏监测：通过光敏传感器检测光照强度
- 红外监测：通过红外传感器检测是否有人
- 漏水监测：漏水传感器检测是否漏水
- 火焰监测：火焰传感器检测是否着火
- 蜂鸣器报警：环境异常情况下蜂鸣器报警
- OLED显示：显示温湿度、光照强度和烟雾浓度
- APP功能：使用机智云APP，通过WIFI模块连接APP来接收环境信息数据与控制指令下发
- 可切换模式：实现手动模式和自动模式的切换，手动模式下可控制灯光和风扇、加热片的开关
2.主要器件
- STM32F103C8T6最小系统板
- DHT11温湿度传感器
- OLED显示屏（4针IIC协议）
- WiFi模块（ESP8266-01s）
- MQ-2烟雾传感器
