Скачать или смотреть Automatic Pump Activation at Low pH

This video presents the automation capability of the developed IoT-based pH control system. The demonstration simulates an acidic condition where the water pH drops below the defined safe threshold of 6.5.

Once the pH reading is detected as too low by the E-201-C sensor and processed by the ESP32 microcontroller, the system automatically activates the water pump through a relay module. The pump then begins circulating water through the filtration system, which contains coral sand to raise the pH level.

This video confirms the following functionalities:
The system continuously monitors pH values in real time.
When pH drops below the threshold (e.g., below than 6.5), the control logic triggers the pump.
The relay module successfully switches the pump ON in response to low pH conditions.
The system is fully automated, requiring no manual intervention to begin the pH correction process.

This demonstration validates the control feature of the project, proving that the system not only detects critical pH levels but also takes corrective action autonomously.
