Update 3 - Week 9 Monday

Week 8 was a productive week for our team. We assembled the PCB and were able to connect and read all of the sensor data simultaneously. Additionally, we designed and printed the enclosure for the indoor monitor.

PCB Assembly

As soon as we received our PCB, we soldered the header pins and other components onto it. After that, we combined our code that we used to test the sensors individually and were able to read data from all sensors at once.

Enclosure 3D Printing

Now that we had the PCB and all of the sensors connected to it, we were were able to measure the dimensions of the entire system and design an enclosure using OnShape.

Further Software Development

After successfully reading data from all of the sensors, we began focusing solely on the user experience and how the data will be displayed to the user. This entails how the data will be displayed on the screen, how many pages there are, and how we can make it easy for the user to interpret the data. We were able to create a simple page layout by the end of the week.

Challenges

Designing and 3D printing the enclosure was challenging and took longer than expected. Because of the sandwich design of the enclosure, the dimensions/tolerances of the friction fit needed to be precise. The initial print was too tight, so we had to adjust the dimensions and re-print. Luckily, the second print had a good friction fit (with some tape to adjust). However, the process took a long time and was a little frustrating due to the minimal availbility of 3D printers.
