According to the abstract released by the Intellectual Property India: "The present invention discloses TerraTouch, an Internet of Things (IoT)-based smart wearable glove system designed for real-time monitoring and analysis of soil and plant health in controlled agricultural environments such as nurseries, greenhouses and research facilities. The invention integrates advanced sensing, embedded processing and wireless communication technologies into a compact and portable glove-based architecture, enabling efficient and user-friendly plant health assessment. The system is built around an ESP32-S3 microcontroller, which serves as the central processing unit responsible for sensor interfacing, data acquisition, processing and communication. The glove incorporates multiple sensors, including a capacitive soil moisture sensor for accurate measurement of soil water content, a soil pH sensor to determine acidity or alkalinity levels affecting nutrient availability and a temperature sensor to monitor ambient environmental conditions influencing plant growth. These sensors work collectively to provide continuous and reliable soil and environmental data. In addition to soil parameter monitoring, the invention integrates a camera module within the glove structure to capture high-resolution images of plant leaves. These images are processed using image processing techniques to identify visual symptoms such as discoloration, texture variation and spot formation, which may indicate nutrient deficiencies or early-stage plant diseases. This dual functionality of combining physical sensing with visual analysis enables a more comprehensive and holistic approach to plant health monitoring. The TerraTouch system operates on a rechargeable battery integrated within the glove, ensuring portability, flexibility and uninterrupted operation in field conditions. The wearable design enhances usability by allowing direct interaction with soil and plants, eliminating the need for multiple separate instruments and reducing manual effort. Furthermore, the system follows a nondestructive monitoring approach, enabling in-situ analysis without harming plant structures or requiring laboratory-based testing. Overall, the invention provides a smart, efficient and scalable solution for precision agriculture by integrating multi-parameter sensing, real-time data processing and IoT-based monitoring within a single wearable device. It enhances accuracy in plant health assessment, improves operational efficiency and supports sustainable agricultural practices in controlled farming environment."
