Taking care of houseplants can be rewarding, but it often requires a level of consistency and knowledge that many people struggle to maintain. Environmental factors such as soil moisture, light, and temperature can vary widely between plant species, and failure to meet these conditions can lead to poor plant health. The Plant Nanny is our proposed solution: a smart plant care system that monitors key environmental variables and helps users optimize plant growth. Using sensors to track soil moisture, light, temperature, humidity, and even detect pests or obstructions, the system sends real-time data to the cloud for analysis. AI-based health evaluation models compare this data against known growth standards for specific plants and trigger automated interventions or offer user suggestions when conditions fall out of range. Plant Nanny also features an integrated water distribution system and camera, allowing it to respond to plant needs while visually tracking growth. All of this is accessible through a user-friendly mobile app that makes plant care more intuitive and engaging. By combining smart home integration, automation, and plant-specific intelligence, the Plant Nanny empowers users to care for their plants more effectively with less effort.
