-MARIS HABITATS is a modular reef infrastructure and environmental monitoring system designed for underwater environments.

The product combines physical reef blocks with a removable smartlogger, allowing it to provide both structural support and long-term environmental data.
  
 The reef blocks are designed to be placed on the seabed and to create surfaces, cavities, and sheltered spaces that may support habitat formation over time. Instead of claiming immediate biological recovery, the product focuses on providing a physical structure that can be used in marine restoration, research, or environmental monitoring projects. The reef blocks are designed to be placed on the seabed and to create surfaces, cavities, and sheltered spaces that may support habitat formation over time.

-The smart sensor box collects environmental data from selected locations around the reef structure. This data can help users understand local site conditions and observe how the reef and surrounding marine environment change over time. The monitoring system is designed to operate with low power consumption and store data locally, reducing the need for continuous communication infrastructure.+The smartlogger collects environmental data from selected locations around the reef structure.

-The final product is intended for organizations such as public institutions, coastal municipalities, research groups, environmental non governamental organizations (NGOs), port authorities, aquaculture operators, and marine infrastructure companies. These customers may use MARIS HABITATS as part of restoration projects, long-term monitoring programmes, sustainability reporting, or environmental decision-making.+The final product is intended for organizations such as public institutions, coastal municipalities, research groups, environmental non governamental organizations (NGOs), port authorities, aquaculture operators, and marine infrastructure companies.

 The basis for this idea is the global environmental challenge of marine ecosystem degradation. The causes of this problem are multiple; the global warming is raising not only the level of the oceans but the temperature of them. This is altering the conditions of most of the underwater eco-systems, and this evolves in multiple species having to migrate from their original environments to new ones. The basis for this idea is the global environmental challenge of marine ecosystem degradation.

 Another important objective is to select materials that are suitable for marine conditions. For the final design, durable and environmentally compatible materials, such as basalt fiber-reinforced concrete, are considered because they can improve resistance to seawater conditions and reduce long-term environmental risks [(FIORE2015)], [(QU2021)]. Another important objective is to select materials that are suitable for marine conditions.

-The project also aims to include a removable monitoring unit. Instead of placing electronics permanently inside the reef structure, the system should use a smart sensor box that can be separated from the main habitat. This makes it easier to check, repair, or replace electronic components without removing the whole reef from the seabed.+The project also aims to include a removable monitoring unit.

 A further objective is to collect useful environmental data. In the final system, the intended parameters include temperature, pressure or depth, pH, and conductivity. This data can help users understand the conditions around the installation site and observe how the surrounding marine environment changes over time. A further objective is to collect useful environmental data.

 For the prototype, the objective is more limited. The prototype is intended to validate the basic sensing and data logging concept under controlled conditions. Due to budget and component availability, it uses a simplified sensor set, including temperature, pressure, and total disolved solids (TDS). The pH and conductivity sensors are reserved for the final product. For the prototype, the objective is more limited.

-Finally, the project aims to reduce unnecessary disturbance to the marine environment. The removable sensor box allows maintenance, battery replacement, and data collection to be carried out without disturbing the main reef structure. This also reduces the risk of leaving failed electronic components underwater.+Finally, the project aims to reduce unnecessary disturbance to the marine environment.

-This section defines the main requirements of the MARIS HABITATS system. The requirements are divided into functional and non-functional categories.

 Because the project separates the final product from the prototype, the requirements are also considered at two levels. The final product is intended for long-term marine deployment, while the prototype is designed to validate the basic sensing and data logging concept under controlled conditions. Because the project separates the final product from the prototype, the requirements are also considered at two levels.

-The main objective of testing the prototype is to verify that the Maris Habitats concept functions as intended under controlled conditions. Since the prototype is a simplified validation model, the tests will focus on the basic operation of the sensor system, the structural stability of the habitat module, and the protection of the electronic components. The final product is intended for long-term marine deployment, while the prototype is mainly used to validate temperature, pressure, and TDS measurements in a controlled environment.+The main objective of testing the prototype is to verify that the Maris Habitats concept functions as intended under controlled conditions. Since the prototype is a simplified validation model, the testing phase focuses on three main aspects: the basic operation of the sensor system, the structural stability of the habitat module, and the protection of the electronic components. The final product is intended for long-term marine deployment, whereas the prototype is primarily used to validate the measurement and data-logging concept in a controlled environment. For this reason, the prototype tests will focus on temperature, pressure, and Total Dissolved Solids (TDS) measurements, while more advanced parameters such as pH and conductivity are reserved for the final product.

 +A structural test will be carried out using SOLIDWORKS simulation tools. This test will be used to analyse how the habitat structure responds to applied forces and to evaluate whether the design can withstand expected mechanical loads. The simulation will help identify possible weak points in the structure and support further design improvements before physical production or deployment. 
 + 
 +A prototype test will be performed in air to verify the basic functionality of the electronic system. This test will confirm whether the sensors, microcontroller, power supply, and data storage system operate correctly before any water-related testing is considered. The purpose of this stage is to reduce technical risk by ensuring that the system can collect and store sensor data under safe and controlled conditions.
  
 +These tests will provide an initial validation of the prototype and help determine whether the system is ready for further development and more realistic environmental testing.
