Nutrient concentration in hydroponic solutions significantly influences plant growth, while manually monitoring and adjusting nutrient levels requires time and accuracy. This study evaluates the performance of an ESP32-based automatic AB Mix control system for monitoring and regulating nutrient concentration in hydroponic solutions. The system uses a TDS sensor to measure ppm levels and an ESP32 to control DC pump actuators that add nutrients or water according to solution conditions. Testing was conducted under two conditions, with initial ppm levels below 700 ppm and above 800 ppm, with three tests for each condition. System performance was evaluated based on its ability to achieve the target range of 700–800 ppm. The results showed that all six tests successfully reached the target range, resulting in a system success rate of 100%. These results indicate that the system can regulate nutrient concentration according to initial ppm conditions and the predetermined target range.
