MyOctopus i2c Barometric Air Pressure Sensor BMP280

Solenoid Valve, 2 Way

Titanium Grade-5 Capsule Enclosure

Description: This project presents an autonomous titanium capsule utilizing the ESP32 microcontroller designed for deep-sea data recovery and emergency telemetry

. It ensures reliable data retrieval and communication in extreme underwater environments, tackling the major challenges of deep-sea exploration and black box recovery.

Description:

1. The core processing unit is powered by the Espressif ESP32 microcontroller.
2. Environmental pressure and depth are precisely monitored using the MyOctopus i2c Barometric Air Pressure Sensor (BMP280).
3. A 2-Way Solenoid Valve is integrated to control the pneumatic/hydraulic release pathways for the internal piston activation system.
4. All components work together to execute emergency telemetry and data rescue operations under deep-sea conditions.

Description: This step includes the MicroPython firmware used for the ESP32 microcontroller

. It continuously reads depth and pressure data from the sensor connected to ADC pin 34, and safely controls the 2-way solenoid valve on pin 15 to trigger the rescue mechanism once the critical threshold is reached.

Description: This step illustrates the complete wiring and circuit schematics (CapsuleCircuit.pdf) connecting the ESP32 microcontroller

to the pressure sensor and the solenoid valve. It details the power distribution and signal routing required for reliable operation in deep-sea conditions.

Description: This step provides the comprehensive research paper and full documentation detailing the architecture, testing phases, and theoretical background of the Autonomous Deep-Sea Forensic Data Rescue System.

Description: This step provides the 3D CAD design files and STL models for the titanium capsule enclosure

. It allows makers and researchers to 3D print or machine the housing components required for deep-sea deployment.
