二，项目简介
随着社会生活水平提高，人们对精神生活的需求日益增长，宠物在日常生活中扮演着越来越重要的角色。然而，宠物饲养也带来了一系列繁琐的责任和挑战。为解决这些问题，本文提出了智能宠物投喂系统的设计框架，结合硬件和软件两个方面，实现了对宠物的智能化管理和远程控制。硬件包括单片机主控单元、传感器、执行部件等，而软件实现了时钟管理、传感器检测、手动控制和蓝牙通信等功能。该系统通过协同工作，为宠物主人提供了便利和可靠的喂食解决方案，充分满足了现代人对精神生活的需求，促进了人与宠物之间的和谐互动。
日常生活中宠物的饲养，闲暇时间可以带着宠物一起散散步，锻炼一下身体，给工作后的闲暇时间增添一些乐趣和放松，人们日常中对宠物的饲养诸如宠物狗的饲养，需要喂食，需要喂水，需要根据气温的变化对宠物进行冷热补偿，需要对宠物的居所通风换气，需要对宠物的居所进行光照强度的调节等，这些事情大多数都需要人为的操作，这样一方面会占据人们的时间和精力，另一方面由于人的惰性和其他事情的干扰导致有时候会遗忘，导致对宠物的照料不及时，这些都是宠物饲养中的遇到的问题，也是令许多宠物饲养者较为纠结的事情。随着科技的进步，智能化逐渐走进人们的日常生活，这也就为宠物的智能化饲养提供了方向。能够实现对宠物的智能化管理，这将会极大的节省人们的工作量，对于宠物饲养的智能化主要体现在如下几个方面，可以根据宠物的生活习性定时喂水，根据宠物居的光线强度动态的补光，能够定时的对宠物居进行的通风换气等，以上也是本次课题的意义和目的所在。
