Day 17: Secure Transport System


After successfully navigating through traps and securing the treasure, the next critical step is to ensure the loot makes it back to the Nebula Raider safely and in pristine condition. As a cadet, you are tasked with creating a secure transport system. This system will monitor the cargo’s conditions and ensure it is safely transported without any damage or tampering.

Components Needed:

Raspberry Pi Pico WH Microcontroller
DHT11 Temperature and Humidity Sensor
MPU-6050 Accelerometer and Gyroscope Module
SRD-05VDC-SL-C Power Relay
LEDs (Green, Red)
Buzzer
Resistors
Breadboard
Jumper wires
Instructions:

Set Up the Circuit:

Connect the DHT11 Temperature and Humidity Sensor to the Raspberry Pi Pico (Data pin to GP2).
Connect the MPU-6050 Accelerometer and Gyroscope Module to the Raspberry Pi Pico using the I2C interface (SDA to GP0, SCL to GP1).
Connect the relay to a GPIO pin on the Raspberry Pi Pico (e.g., GP3) to simulate securing the cargo.
Connect the Green LED to a GPIO pin on the Raspberry Pi Pico (e.g., GP4) with an appropriate resistor.
Connect the Red LED to a GPIO pin on the Raspberry Pi Pico (e.g., GP5) with an appropriate resistor.
Connect the buzzer to a GPIO pin on the Raspberry Pi Pico (e.g., GP6).
Use jumper wires to make all necessary connections on the breadboard, ensuring a secure and organized setup.

Write the Code:

Open your coding environment and write the following Python code to create the secure transport system.

Test the System:

Upload the code to the Raspberry Pi Pico and run it.
Simulate different conditions by manipulating the temperature, humidity, and accelerometer readings to test the system’s response.
Ensure the LEDs and buzzer provide accurate feedback based on the conditions, and the relay simulates securing the cargo.

Learning Outcomes:

Sensor Integration: Learn how to connect and use multiple sensors (temperature, humidity, accelerometer) with the Raspberry Pi Pico.
Condition Monitoring: Understand how to monitor and respond to environmental conditions to ensure the safe transport of cargo.
Microcontroller Programming: Develop skills in writing code to integrate multiple sensors and output devices.
Extension Ideas:

Data Logging: Implement data logging to record the conditions during transport for further analysis.
Remote Monitoring: Create a web interface to remotely monitor the conditions and status of the transport system.
Advanced Security: Add more security features, such as RFID tags, to ensure the cargo is not tampered with during transport.
By completing this project, you will have built a secure transport system to ensure the loot is safely returned to the Nebula Raider in optimal condition. This system will help maintain the quality and security of the valuable treasure during transit.
