SMART FERTIGATION SYSTEM USING NODEMCU ESP8266

electrical engineering

This paper introduces an Automated Fertigation System, which is designed and implemented using the NodeMCU microcontroller. The system incorporates an automatic mixing mechanism controlled by the NodeMCU, facilitating the precise blending of fertilizers with water based on soil moisture levels detected by a sensor. This project is classified into two main parts. The first part focuses on maintaining the optimal moisture level in the soil. A soil moisture sensor is utilized to detect the moisture content in the soil. The sensor's output is then transmitted to the NodeMCU ESP8266 microcontroller, which determines whether additional water needs to be pumped. The second part involves designing a control system for the mixing and delivery of fertilizers. Utilizing the built-in Wi-Fi capabilities of the NodeMCU ESP8266, the project facilitates wireless communication with the Ubidots application, enabling real-time monitoring and storage of moisture sensor data. This showcases the capabilities of IoT technology in agriculture. When the smart fertigation system is implemented, it enhances water and fertilizer utilization efficiencies, resulting in savings of labor, capital, time, and energy, while also increasing production and productivity.
