Design Efforts 

​

• Design goal: Design an enclosure to combine raspberry pi, sensors, and screen to read/save the environment data and achieve real-time plotting.

​

• Hardware updates since 33% build: Change assembly of components in enclosure, using detachable tripod instead of wood base (portability), ensure entire system can run off 12v vehicle electrical supply, switched to analog output anemometer

​

• Software updates since 33% build: Save readings as csv files/txt files and plot real time data using Pandas and Matplotlib, we can plot temperature and voltage data in one graph with time.

Purchasing Plan

Manufacturing Plan

Parts Received/Manufactured

• Sub panel and screen base have been manufactured and  some holes have been drilled. 
• Anemometer has been received and will start building code this weekend. 
• Cooling fan mount will be drafted, and 3D printed soon. 

More Parts Received/ Manufactured

• Shunt Resistors will be mounted to sub plate
• Voltage Amplifier will be used to amplify voltage going from Raspberry Pi to Anemometer
• Perf Board will be used for voltage reduction circuit and pressure sensor

Enclosure 

Manufacturing Plan Cont.

• Shop Training required for drilling of holes in component base to mount Raspberry Pi, shunt resistors, and circuit components. Screen base will be 3D printed.

​

Final CAD Designs

Demonstration

• So far, the team has successfully collected environmental data using raspberry pi, including temperature, pressure, wind speed, and voltage.

​

• The enclosure has been modified with holes on the wall during the manufacturing process for voltage input and other user interface ports

​

• Saving data to local csv/txt files has been achieved by the team for time, voltage, temperature, and other channels.

​

• Real time plotting has been achieved for temperature and voltage channels in separate graphs.

Rough Live plotting of Voltage vs. time and temperature vs. time

• We will massage the error out of the graphs in the coming weeks and add more graphs for Barometric Pressure vs time and Wind speed vs time
• Still need to figure out how to simultaneously plot and record data to a txt file

Testing Plan

• Test Temperature sensor, pressure sensor, and anemometer to produce measurement uncertainties and calibration values for each sensor (see how accurate the readings are).
• Test Voltage sensing circuit with variable load and battery to ensure correct voltages are being measured.

Gantt Chart Update

• The Gantt Chart is used by the team to plan work around deadline and allocate resources. It has been updated this semester based on the client requirements.
