摘要
在宠物饲养领域，猫舍环境的舒适与稳定对猫咪的健康成长至关重要。传统的猫舍管理多依赖人工照料，不仅耗费时间和精力，还存在环境调控不及时、喂食喂水不规律等问题，难以满足现代化科学养猫的需求。
基于 STM32F103C8T6 单片机的智能猫舍系统，整合了 DS18B20 温度检测模块、MQ-135 氨气检测模块、时钟模块、HX711 重量检测模块、液位检测模块、按键、OLED 显示屏、WIFI 模块及执行设备（空调、通风装置、加食设备、加水设备、声光报警装置等），实现了猫舍环境的自动化监测与智能调控。系统核心功能包括：通过 DS18B20 实时监测温度，当温度低于设置最小值时开启空调制热模式，高于设置最大值时开启制冷模式；通过 MQ-135 检测氨气值，大于设置最大值时打开通风装置；借助时钟模块获取时间，支持按键修正时间，且可设置三个带使能位的投喂时间；通过 HX711 检测食物重量，投喂时间到时，若重量低于设置最小值则自动加食，直至重量大于设置最大值后停止，并触发声光报警三声提醒宠物吃食；通过液位检测模块检测水位，低于设置最小值时自动加水，直至水位大于设置最大值停止；支持通过按键设置各参数阈值，以及手动控制各器件开关；通过 OLED 显示屏实时显示各项测量数据；利用 WIFI 模块将数据发送至手机端，手机端可设置各阈值并远程控制各器件开关。
该系统的实现，有效提升了猫舍管理的自动化与智能化水平，减少了人工干预，为猫咪提供了舒适、健康的生活环境，同时为同类宠物饲养智能化设备的研发提供了参考，具有较高的实际应用价值。

ABSTRACT
In the field of pet breeding, a comfortable and stable environment in cat houses is crucial for the healthy growth of cats. Traditional cat house management mostly relies on manual care, which not only consumes time and energy but also has problems such as untimely environmental regulation and irregular feeding and watering, making it difficult to meet the needs of modern scientific cat raising.
The intelligent cat house system based on the STM32F103C8T6 microcontroller integrates DS18B20 temperature detection module, MQ-135 ammonia gas detection module, clock module, HX711 weight detection module, liquid level detection module, buttons, OLED display, WIFI module and executive devices (air conditioner, ventilation device, feeding device, water adding device, sound and light alarm device, etc.), realizing automatic monitoring and intelligent regulation of the cat house environment. The core functions of the system include: real-time temperature monitoring through DS18B20, turning on the heating mode of the air conditioner when the temperature is lower than the set minimum value, and turning on the cooling mode when it is higher than the set maximum value; detecting ammonia gas value through MQ-135, and turning on the ventilation device when it is greater than the set maximum value; obtaining time with the clock module, supporting time correction through buttons, and setting three feeding times with enable bits; detecting food weight through HX711, and when the feeding time comes, if the weight is lower than the set minimum value, automatically adding food until the weight is greater than the set maximum value, then triggering three sound and light alarms to remind the pet to eat; detecting water level through the liquid level detection module, automatically adding water when it is lower than the set minimum value until the water level is greater than the set maximum value; supporting setting various parameter thresholds through buttons and manually controlling the on/off of each device; real-time display of various measurement data through the OLED display; sending data to the mobile phone via the WIFI module, and the mobile phone can set various thresholds and remotely control the on/off of each device.
The implementation of this system effectively improves the automation and intelligence level of cat house management, reduces manual intervention, provides a comfortable and healthy living environment for cats, and also provides a reference for the research and development of similar intelligent equipment for pet breeding, with high practical application value.
