I am designing IoT based Container Tracking System and want your sugestions about what sensors should i use, and what would be the communication medium for transmition of data.
I want to get
1) real time location
2) get data if the container is opened
these are the primary parameters that i want to get. Apart from that i want to make it solar operable so it wont need a battery change.
note: by container i don't mean only the containers that come on ports, but any kind of containers (eg, Barrels).
