二、项目简介

1.功能详解

基于STM32的智能坐垫|座椅

功能如下：

1. 使用STM32F103C8T6单片机作为主控单元
2. 通过DHT11检测温湿度数据，当温度不在设定的范围内，则控制加热和散热
3. 通过按键设置时长、温度上下限值、手动控制加热、散热、模式切换
4. 通过HX711检测重量，当重量不为0，则表明有人坐在坐垫上，此时开始计时，当计时时间超过设定的最长时间，则语音提醒“久坐多时，注意起身运动”
5. 通过OLED显示测量数据
6. 通过蓝牙模块，可将坐下时长、温湿度发送到手机端，手机端也可控制加热、散热、模式切换

2.主要器件

• STM32F103C8T6单片机
• OLED 屏幕
• DHT11温湿度传感器
• HX711称重传感器
• JR6001语音模块
• BT04A蓝牙模块
• 继电器
• 风扇模块
• PTC加热片
