Real-Time Monitoring System for Measurement Of Soil Fertility Parameters in Smart Farming Applications

The real-time-based pH and soil moisture monitoring system is one of the solutions for monitoring soil fertility parameters for large areas. The research aims to monitor the pH and soil moisture values in a real-time website-based platform. The system used the Wemos d1 R2 microcontroller that has been planted with the esp8266 Wi-Fi module so that it will connect to the internet or access points wirelessly. The wireless connection method used to avoid cable installation and maintenance, which is complicated and expensive. Wemos d1 R2 also used as a web server using HTTP as a protocol. The sensor used in the system is the FC-28 sensor to measure soil moisture and ETP-110 to measure pH values. The results of pH and soil moisture measurements are displayed on the website. The results of the comparison of soil pH measurements with a soil analyzer as a control and pH sensor ETP-110 showed the average difference 1.58, while the comparison of FC-28 and Soil Analyzer measurements gave a difference of 0.6% for humidity value. This research successfully built a system that can display data on the website whose value is the same as the value in the database.
