This week we did a lot of prep work for getting started on building. We were able to get some power consumption analysis going as well as further part analysis. For AWS, we were able to get AWS IOT working and connecting our esp8266 to AWS core. We also spent a good portion of the week planning our design presentation. In terms of front end, we got a simple UI going that displays needed information on the occupancy status in the UC. We have some ongoing conversations for storing information from our sensors and how we should identify each table, but that is not a significant risk.
The biggest risk so far is still regarding the sensors. However, after doing some power consumption analyses, we discovered that we would have to do a bit more design changes to the hardware in order to account for the battery lasting 55 hours. This didn’t necessarily change the costs, but we did have a more in depth conversation of what parts we actually need to support this current load. We also discovered that there need not be a big change on our existing schedule, and we are moving forward at a good pace.
