AI Pet Wellness Suite is an AI-powered smart habitat for dogs and cats that transforms a pet's everyday living space into a personalized wellness environment. Non-contact mmWave radar, thermal imaging, RGB-D vision, a pressure-sensing floor, and environmental sensors continuously capture biometric, behavioral, spatial, and environmental data without requiring the pet to wear a device. Edge AI fuses these signals to learn each pet's individual baseline and detect meaningful changes in respiration, sleep, activity, posture, weight distribution, thermal patterns, and stress-related behavior. Unlike conventional pet cameras or single-purpose monitors, its closed-loop AI Care Engine goes beyond passive monitoring by using real-time health, behavioral, and environmental data to automatically optimize temperature and airflow while alerting owners to meaningful changes and providing understandable long-term wellness trends. The result is continuous, individualized care that helps owners recognize changes earlier while maintaining a safer, more comfortable, stress-conscious living environment for their pets.
