Agricultural IoT Application Solution

The Agricultural Internet of Things (AIoT) plays a crucial role in modern farming by integrating real-time data monitoring and automated control systems. It allows for the seamless collection and analysis of environmental parameters, such as temperature, humidity, light intensity, soil pH, and CO₂ levels, enabling precise management of greenhouse conditions. This technology not only enhances crop yield and quality but also helps regulate growth cycles, leading to improved economic returns. In a greenhouse control system, various IoT-enabled sensors—like temperature, humidity, pH, illuminance, and CO₂ sensors—are used to monitor critical factors that influence plant growth. These sensors collect data continuously, ensuring that crops receive optimal growing conditions. With remote control capabilities, agricultural technicians can manage multiple greenhouses from a central location, improving efficiency and reducing manual labor. Wireless networks further support this process by allowing real-time adjustments based on collected data, ensuring the best possible environment for plant development. The widespread application of AIoT in agriculture involves creating extensive sensor networks that gather and analyze data. This enables farmers to detect issues early and accurately locate problems, making farming more efficient and less dependent on traditional methods. As a result, the industry is shifting from a machine-centric model to one that is information- and software-driven, utilizing advanced tools like automation, smart devices, and remote controls. **Agricultural IoT Application Solution** **I. Introduction to the Intelligent Agricultural Greenhouse IoT Solution System** Greenhouses are essential for extending the growing season and increasing yields, especially during unfavorable weather conditions. They provide controlled environments for cultivating vegetables, flowers, trees, and other plants. Because of this, maintaining precise environmental conditions is vital for successful crop production. Traditionally, farmers have relied on their senses to decide when to water, ventilate, or heat the greenhouse. However, this approach lacks scientific accuracy. With the rise of the information age, there is now greater emphasis on collecting and analyzing environmental data inside greenhouses, such as air and soil temperature, humidity, CO₂ levels, and light intensity. The integration of IoT technology has made it possible to achieve more efficient and accurate management of these conditions.  *Figure: Greenhouse planting scene* In a typical greenhouse setup, IoT technology is used to create a wireless network of sensor nodes. These nodes measure soil moisture, composition, pH, temperature, humidity, light intensity, and CO₂ levels, among other factors. By analyzing this data, the system can automatically adjust the greenhouse environment, including irrigation, fertilization, and climate control, to provide the best possible conditions for plant growth. For larger agricultural parks, data from wireless sensor nodes is aggregated, stored, and analyzed. This allows for comprehensive monitoring of all test points, with visual charts and graphs displayed for easy interpretation. Users can also receive alerts via sound, light, or SMS, depending on the specific needs of the crops, enabling efficient and remote management of greenhouses. Moreover, IoT technology supports different stages of greenhouse production by analyzing plant performance and environmental variables at each phase. This feedback loop allows for continuous improvement and more precise management, ultimately resulting in higher-quality agricultural outputs. **II. Key Components of Top’s Intelligent Agricultural Greenhouse IoT Solution** 1. **Data Collection** Using an IoT system, various sensors can be connected to monitor soil temperature, humidity, nutrient content (N, P, K), pH, precipitation, air temperature and humidity, pressure, light intensity, and more. This data helps determine the ideal growing conditions, and real-time adjustments can be made to temperature control, irrigation, and other systems based on the collected parameters.  *Figure: Environmental information collection node in a greenhouse* 2. **Intelligent Control** Through wireless communication, the control room can be connected to the greenhouse's control cabinet. Operators can manage fans, external and internal shading, drip irrigation, side windows, wet curtains, and fertilizer sprinklers through a centralized console, enabling full remote control and management of the greenhouse environment.  *Figure: Intelligent control system interface*  *Figure: Remote control via smartphone*
