This paper presents the development of an advanced fertilizer system for strawberry cultivation, utilizing Internet of Things (IoT) technology, aimed at enhancing productivity and improving fruit quality in low-land strawberry farming. The system automates the entire fertigation process, including the precise mixing of fertilizer and irrigation, with the ability to monitor and control the process remotely. Key components of the system include a submersible water pump, dosing pumps, relays, an ESP32 microcontroller, a MAX485 RS485 to TTL Serial Converter, and a comprehensive 7-in-1 soil parameter sensor. This soil parameter sensor monitors essential soil characteristics, including pH, electrical conductivity, nitrogen, phosphorus, potassium, moisture, and temperature, directly in the root zone. A user-friendly web-based GUI has been developed, enabling users to monitor and control the cultivation process remotely. Throughout the cultivation period, the entire system operated reliably, showcasing its potential to improve strawberry plant growth.
