This week, Jaehyun, John, and I continued to refine our parts list.
We specifically focused on our planned LoRa network, researching how to use LoRaWAN and LoRa, as well as looking into how we wanted to put together our LTE board setup.
For the cellular network we are planning to use for communication between the hub and the web UI, I looked into whether the service provider would be compatible with our plan of an LTE board with a sim card.
The following images are screenshots of the chatlog I had with one of the service representatives.
My team and I concluded that should the module we chose come with an IMEI (which we are fairly sure it does), it should be compatible with the service provider.
This week I also worked on refining my delivery of the Proposal Presentation, which went smoothly.
In addition to this, I reached out to one of CMU’s makerspaces about the materials that are available for 3d printing, as we are planning to 3d print parts of our sensor box. I have obtained a sample print of their doped PLA that I plan to look over with my teammates next group meeting.
I also got the names of two people we may want to reach out who have personally worked on air quality monitoring sensors, instruments, and even the calibration of said sensors.
With the positioning of the POGOH bike’s lights, there is also a possibility that our current sensor box form will have to adjust accordingly. I plan to discuss this with my teammates next meeting as well.
As for the data visualization map, we plan to use leaflet.
My progress is on schedule so far. I have started looking into how to make the data visualization map, and have been assisting with making sure we are ready to order our parts (presumably) next week.
Next week, I plan to prototype the sensor box with a POGOH bike on campus as a reference point, and nail down some of the specific dimensions restraints. I hope to also have a rudimentary data visualization by next week.
