Dynamic Temperature, Humidity, and Lighting System for Smart Home Based on Fuzzy Logic

Smart home has always been a hot topic, and a good smart home system is not common. It is clear that ordinary houses and apartments can be transformed to become smart homes by adding smart products and applying artificial intelligence (AI). Besides, using smart phones and personal computers to remotely control the smart home system or some parts of it has always been one of the main users’ requirements, especially to those living with disabilities. In addition, among all the household devices, the air conditioner is one of the most power-consuming products. Because of that, a special attention should be given to finding a smart home system that can use the air conditioner efficiently. An AI approach, called fuzzy logic, may be used for such task. In this study, a simple, light-weight, and low-cost smart home system is designed and tested to perform several tasks to improve the human life. The system uses fuzzy logic to turn on the air conditioner when needed as well as change its modes to better meet the human needs. It can also control a few other household products, such as the lighting devices. Additionally, some security measures are introduced, e.g., if a stranger approaches the house door, a light or camera can be activated, and a text warning is presented on a light-emitting diode device.
