单片机设计_室内环境智能监测系统(STM32 OLED ESP8266 DHT11 MQ-2 加湿器)
想要更多项目私wo!!!
一、电路设计
室内环境智能监测系统
主要功能:
1.检测空气温湿度
2.检测光照强度
3.检测烟雾浓度
4.数据显示在手机端和设备OLED屏幕上
5.当空气温度高于设定的阈值时，风扇开启
6.当空气湿度低于设定的阈值时，加湿器开启
7.当光照强度低于设定的阈值时，灯开启
8.当烟雾浓度高于设定的阈值时，风扇开启蜂鸣器开启
9.以上5～8条的阈值可以在手机端控制更改或者设备的按键进行更改
10.设备具有手动和自动两种模式，可以通过手机或设备端更改
11.可以用手机远程控制设备
手动模式下可以控制风扇，加湿器，灯，蜂鸣器的开关
自动模式下就是以上5～8条的阈值自动控制
