Need to ensure that the prototype will operate in temperatures between 37ºF to 80ºF. We set up the system to run tests. We created a lower temperature setting in order to simulate the warehouse's refrigerated environments and ran tests. This was challenging due to not being able to actually go into one of their warehouses due to coronavirus disease 2019 (COVID-19) restrictions. The lowest temperature we were able to test the prototype was around 40ºF which was close to 37ºF. Operating at the 80ºF was much simpler to test due to there being multiple days within the 80ºF temperature range.
