二、项目功能简介

【开源】STM32单片机智能药盒/老人用药管理系统（代码+原理图+仿真

功能介绍：
1、 LCD1602液晶显示当前时间(DS1302模块)、温湿度(DHT11模块)、药品重量(HX711压力模块)。
2、按键可独立设置3次吃药时间、药品类目和药品数量。
3、到了吃药时间后液晶闪烁提醒吃药数量和类目，蜂鸣器进行声光报警提示。
4、该吃药时，红外感应当前药盒是否打开，药盒打开后自动取消报警和液晶显示提示。
5、药品数量、定时时间可以掉电存储，重新上电无需重新设置。
6、配备蓝牙手机APP，功能如下：
①远程显示当前温湿度、药物重量、吃药时间。
②可以远程设置三次吃药时间、药品种类、药品数量等信息。
③吃药时间到时，手机震动提醒并语音播报：“吃药时间到了，请及时吃药”，点击“已吃药”停止震动和播报。
