Hi all, need a little guidance on designing a solution.
Problem: A deep freezer manufacturing and ice cream distribution company requires a solution to manage it's freezers spread across whole country (on retailer shops). 3 requirements are there:
- Get real-time location of all their deep freezers on a cloud server.
- Replace the barcodes placed on DFs with some other thing so that the sales team (order takers for retail shops) do not have to use barcode scanners to identify the deep freezer. Instead they want a smartphone based solution.
- Log the temperature of deep freezers and get on cloud server.
Each deep freezer's ID, location and temperature log should be available real-time on a cloud server. Now the question is, what sort of sensors/controllers should be used? how to transmit data from a DF over broadband? How to establish communication between the DF and sales person's smartphone?
Any equipment can be installed within the DF during it's manufacture.
Thanking all in anticipation and looking forward to some nice discussions on the possible approaches.
