Analysis of the Data Acquisition and Transmission System Scheme"},"content":{"rendered":"

This system is designed for the acquisition, storage, and real-time transmission of data, with a focus on measuring environmental variables and fluid behavior within the experiment.<\/p>\n

    \n
  1. Processing and Control Unit<\/u><\/strong><\/li>\n<\/ol>\n

    The system is based on the\u00a0ESP32-WROOM-32, a microcontroller with WiFi and Bluetooth connectivity, used to process and manage information from multiple sensors. This central module:<\/p>\n

      \n
    • Receives data from sensors via\u00a0I2C,\u00a0SPI, and\u00a0UART\u00a0protocols.<\/li>\n
    • Stores information on a\u00a0microSD card.<\/li>\n
    • Transmits data to the ground station using an\u00a0RFD900X radio module.<\/li>\n<\/ul>\n
        \n
      1. Integrated Sensors<\/u><\/strong><\/li>\n<\/ol>\n

        The scheme now incorporates a variety of strategically distributed sensors:<\/p>\n

          \n
        1. a) Pressure and Temperature Sensors (GY-MS5837-30BA):<\/li>\n<\/ol>\n
            \n
          • Locations: Two sensors placed at different points in the fluid system.<\/li>\n
          • Function: Measure the pressure and temperature of the liquid inside the container, allowing analysis of changes due to acceleration, altitude, and other environmental factors.<\/li>\n
          • Communication: Connected to the ESP32 via\u00a0I2C.<\/li>\n<\/ul>\n
              \n
            1. b) Inertial Sensor (BNO055):<\/li>\n<\/ol>\n
                \n
              • Function: Combines an accelerometer, gyroscope, and magnetometer in a single module.<\/li>\n
              • Use: Measures orientation and detects vibrations or impacts experienced by the system.<\/li>\n
              • Protocol: Uses\u00a0I2C\u00a0to send data to the microcontroller.<\/li>\n<\/ul>\n
                  \n
                1. c) Water Level Sensor (ZP5210):<\/li>\n<\/ol>\n
                    \n
                  • Innovation: This new sensor detects the liquid level in the container using a magnetic float.<\/li>\n
                  • Importance: Ensures the fluid volume remains stable and allows detection of leaks or evaporation during the experiment.<\/li>\n
                  • Connection: Integrated into the system through a digital input.<\/li>\n<\/ul>\n
                      \n
                    1. Storage Module (MicroSD):<\/u><\/strong><\/li>\n<\/ol>\n
                        \n
                      • Function: Stores sensor data as a backup in case of transmission loss.<\/li>\n
                      • Protocol: Connected to the ESP32 via\u00a0SPI.<\/li>\n<\/ul>\n
                          \n
                        1. Wireless Communication (RFD900X Radio Module):<\/u><\/strong><\/li>\n<\/ol>\n
                            \n
                          • Frequency: 900 MHz (LoRa).<\/li>\n
                          • Range: Long-range communication with the ground station.<\/li>\n
                          • Protocol: UART for data transmission from the ESP32.<\/li>\n<\/ul>\n
                              \n
                            1. Power Management:<\/strong><\/li>\n<\/ol>\n
