 === 1.6.1 Functional Requirements ===
-The system must collect environmental data in real time, including water temperature, pH, and turbidity, using sensors at predefined intervals.
+The system must collect environmental data in real time at predefined intervals. The measured parameters include water temperature, pressure (depth), pH, and conductivity.
-The collected data must be transmitted wirelessly to a cloud-based platform to enable real-time monitoring and analysis.
+The collected data must be stored locally using a data storage unit such as an SD card. This allows continuous data recording without relying on external communication infrastructure.
-Energy consumption must be minimized. This is achieved through the use of energy-harvesting methods, such as solar or wave energy, combined with low-power modes like Deep Sleep.
+Energy consumption must be minimized to extend operational lifetime. This is achieved by using low-power operating modes, where the system remains active only for short periods during measurement cycles.
-The physical structure must include cavities and textured surfaces to support the attachment and growth of marine organisms, promoting biodiversity. [(Graham2013)], [(PHAROS2024)].
+The system must perform measurements periodically, with a typical interval of one hour. During each cycle, the system remains active only for the time required to stabilize sensor readings and store data.
+The physical structure must include cavities and textured surfaces to promote the attachment and growth of marine organisms, supporting biodiversity. [(Graham2013)], [(PHAROS2024)].
