Here is a more detailed description of the prototype so you can get a more accurate picture.: --- **Detailed Description of the Tunnel Vibration Monitoring Prototype:** The prototype of the vibration monitoring system is a compact and functional unit, specifically designed to be installed on the interior walls of the Naval School tunnel. Its structure is robust and optimized to operate in the tunnel environment.. 1. **Protective Box:** - The protective case of the device is rectangular in shape, with dimensions of approximately 25 cm long, 12 cm wide, and 6 cm deep. It is constructed of durable ABS plastic, in a matte black colour to minimise visibility in the tunnel environment. - The box is airtight, with a rubber seal around its inner edge to protect the internal electronic components from dust and moisture that might be present in the tunnel. 2. **Internal Distribution:** - **Arduino Uno**: Inside the box, The Arduino Uno is fixed to the base using screws and metal standoffs, which provides stability and adequate space for ventilation. - **18650 batteries**: The batteries are arranged in a special holder that allows for easy removal and replacement.. They are lined up side by side at the bottom of the box., connected by low resistance cables to optimize power delivery. - **Bluetooth Module**: Located on the top of the box, The Bluetooth module is connected to the Arduino using Dupont cables. A small antenna protrudes through an opening at the top of the box., Optimized to keep the wireless signal strong and stable. - **cabling**: All internal cables are organized with nylon cable ties to prevent tangles and ensure a reliable connection.. Standard connectors are used for easy maintenance and function testing.. 3. **Senso External Mount
