The hydroponic systems often lack comprehensive monitoring sensors and can be cost prohibitive, leading to suboptimal crop yields. To address these limitations and enhance crop quality, there is a growing need for advanced monitoring solutions tailored to the specific parameters of plant growth. The objective of this project is to enhance solar powered hydroponic plant growth through the implementation of a smart control and management system. In this project the system can be controlled and monitored from any location using a smartphone application. This system will send information through Blynk application to the ultimate user regarding the pH level, temperature, humidity, water level, voltage and current value from the solar panel. There will also be notifications regarding the water level. In addition to that, internet of things (IoT) that is the Blynk application gives its users the opportunity to turn on or off the LED light automatically, which in turn makes it possible for the vegetables to carry out photosynthesis even on days when the sky is cloudy or it is raining. Finally, the water flow can be controlled by turning the water pump on and off from the mobile phone. All parameters will be display on the Blynk application, while only air quality, air temperature, air humidity and pH will be shown on the LCD. The results for this hydroponics system will be as for value of the temperature will be within the range of 24 to 32 For humidity the range will be within 60% to 80% RH (Relative Humidity). As for the value pH level it will be in the range of 5.5 to 7. The water level sensor can be monitor by the Blynk application as water low or high by sending a notification to the application. The voltage that the sun produce for the solar panel 20 Watt or 18 V is that 12 V and the current will be less than 1 amperes the this system.
