一、视频展示

基于stm32的室内环境监测装置设计与实现 -视频分享

二、项目简介

主控：STM32F103C8T6
显示：OLED显示屏
传感器:
DHT11温湿度传感器
mq2烟雾传感器
光照传感器
esp8266wifi透传模块
led灯
加湿继电器+除湿继电器+加温继电器+降温继电器
声光报警：蜂鸣器＋led灯
功能：
1、屏幕实时显示当前温湿度，烟雾浓度，光照数据。
2、可按键设置阈值，包括最高温度阈值，最低温度阈值，最高湿度阈值，最低湿度阈值，最大烟雾浓度，最低光照。
3、当温度高于设定的阈值时，模拟的空调设备会自动打开进行降温，一旦温度低于阈值便关闭空调停止降温；湿度低于设定阈值时，外接的加湿器设备会开启进行加湿，高于阈值时则关闭加湿器停止加湿；烟雾浓度高于设定阈值时，蜂鸣器报警设备会打开发出警报，低于阈值时便关闭蜂鸣器报警设备停止报警；光照强度低于设定阈值时，补光设备会打开进行补光，高于阈值时则关闭灯光停止补光。
4、手机连接单片机可接受单片机数据，并可控制单片机。
