前言
随着智能化的发展，“智慧”一词常映入我们的眼帘，目前我们的生活中很多会运用嵌入式技术，将实现功能的程序写入单片机中，因环境的改变通过单片机控制做出相应的动作，在本项目中主要实现智慧农业的实现，主要使用STM32进行开发。

提示：以下是本篇文章正文内容，下面案例可供参考

一、项目介绍
智慧农业实现的功能是首先进入开机界面，界面展现的是一个取模后的开机动画，及欢迎文字，经过一定的时间后，变成主界面，再通过按键中断控制切换成数据采集界面，采集对应的农业环境的光照、温度、湿度的数据，当采集的数值超过阈值后会进行蜂鸣器的响应等，在查看完数据后可通过按键中断进入关机的程序，跳入关机界面。

二、项目技术
OLED屏显、IIC协议、USART协议、中断、取模、DHT11温湿度采集、ADC光照采集、stm32f407vet6开发板等
三、项目代码及实现结果
