基于STM32单片机的恒温药箱的设计 -视频分享

二、项目简介

题目：基于STM32单片机的恒温药箱的设计

主控：STM32F103C8T6

显示：1062屏幕

DS18B20温度传感器

加温继电器

降温继电器

语音：JQ8400

三按键

DC电源

红外光电

DS1302时钟模块

功能：

1、程序设置7点，12点，17点语音播报提醒提醒用户吃药（吃药时间到）

2、红外监测药品数量，红外每被遮住一次，药品数量减1

3、可按键设置温度阈值，当实际温度低于阈值时，进行继电器加热。

4、当温度超过阈值，进行继电器降温，进行声光报警。

5、红外传感器检测药盒是否被打开。

三、原理图设计

四、PCB硬件设计

五、程序设计
