Soils naturally contain many nutrients like nitrogen, phosphorous, and potassium.[1] These nutrients allow plants to grow. When soil nutrients are missing or in short supply, plants suffer from nutrient deficiency and stop growing. When the nutrient level is too low, the plant cannot function properly and produce the food necessary to feed the world's population In India many farmers are still using the traditional methods for agricultural fields. These traditional methods can be replaced using the current technology. In rural agricultural regions, where farming practices often form the backbone of the community's livelihood, there is a critical need for an IoT-based soil monitoring system that addresses the unique challenges faced by farmers. This system must empower rural farmers with access to technology that can enhance their productivity, sustainability, and economic well-being This research presents a groundbreaking approach to precision agriculture through the development and integration of an advanced agricultural sensor hub. [2] The device incorporates NPK (Nitrogen, Phosphorus, Potassium), moisture, and DHT-11 sensors, synergized by a microcontroller and IoT connectivity. The NPK sensor enables precise monitoring of soil nutrients, while the moisture sensor ensures optimal irrigation management. The DHT-11 sensor captures environmental data crucial for understanding climatic conditions affecting crop growth. An IoT module facilitates real-time data transmission, enabling remote monitoring through a user-friendly web interface. This integrated system empowers farmers with timely insights for informed decision-making, promoting sustainable farming practices. The comprehensive circuit diagram and experimental setup are detailed in the methodology.
