Sometimes waste containers are also located indoor (e.g. parking lots, enclosures) so I really do need a solution that can power it either way without the use of any external energy sources. There's some technology out there like this already, and I know they all use batteries.
Our company doesn't own its own trucks, but contracts them, so getting rid of inefficient waste hauling (i.e. when there is a container collected always three-quarter empty) reduces costs significantly as you can make less runs.
I have 10 devices atm doing all of this (minus the camera at this point) working perfectly fine. The only bottleneck left is the battery as the 2Ah battery powers it for roughly 4 months only. I'll see how the LiSOCl2 performs - from what Ive heard so far theres a very good chance it will work great for this
