Temperature and Humidity Sensor With Arduino (N)

the sensor ( DHT11 ) collects humidity and temperature. Then takes that information and stores it onto an SD card which we can analyze in google docs.

Step 1: Starting Off (D)

Search around the internet and look for designs and how to wire the Arduino correctly. You will need to print off the step by step instructions on how to put the model together. This will be very helpful as you will be able to go back and find a mistake that you may have made if you made any.

Step 2: Design Brainstorm (N)

The first thing you should do is think of a sturdy design for your CubeSat. You will need to draw out a design and flesh out the details.

so for the design I found a file of a cube sat 3d printed it than traced it on paper.

Step 3: Final Design (D)

You should have each of your group members draw out a design of what they think would be the best for the cubesat. You will then come together and talk about why you chose that design, then add in the best design from everyone's design to make the best design needed.

Step 4: Printing (N)

You will then be able to print the final design with the 3-D printer. It may take a few hours but its worth it as it's very strong and durable.

fist I had to find an online STL file that the 3d printer can understand than I tweak the file a little bit to best fit our design than I had to take that STL file and splice the file using program called repitier ( spicing is what tells the 3d printer how to mover) than after that I prepared the 3d printer, removed old filament, warmed the bed, and preheated the extruder. After that I printed off the 4 side bars, the 4 side plates, and the 2 top pieces.

Step 5: Wiring (K)

The next step will be to start the wiring for the Arduino. Our guidelines were that we needed to gather data with a specific sensor of our choosing, and have that data upload onto an SD card. We chose the DHT 11 temperature and humidity sensor since we are supposed to be surveying a "planet".

Step 6: Programming (K)

We found and import the DHT 11 library to our code. Their might be a few little things that you will have to change for the sensor to collect data. For our code we used most of the code from

Step 7: Fritzing (N)

You will have to complete a diagram to show a design of what your Arduino looks like and where the wires go to and come from.

Step 8: Final Touches/changes (D,K,N)

Now you will need to talk to your team and see if everything is going ok and is working correctly. if something isn't working at a 100% now is the time to hurry up and change it.

Step 9: Testing (D)

You will have to perform 3 different tests to see if your CubeSat will be able to handle the real flight.You will have to make sure your CubeSat can pass the flight test, the shake test, and the constraint test.

Step 10: Constraints Test (N)

The first test you will have to perform and pass is the constraints test. Your overall mass can not exceed 1.3kg

Step 11: Flight Test (D,K,N)

You will have to perform a flight test that simulates orbiting mars for 30 seconds with no malfunctions or anything breaking.

Step 12: Vibration Test

The third and final test you will have to perform is the vibration test. You will have to plug in the Arduino to the battery and wait for the light to turn on. You will then perform the vibration test at 25volts for 30 seconds, when the time is up you will check the Arduino and see if everything is still working properly.
