I'm pretty sure they don't: source I've helped move people's stuff in and out of a couple of different places. My experience is very limited, so if you have more data points where you have seen such things, please share.
I can speak for U-Haul specifically because I have used them and a customer can see the sensors in their unit. The sensors are deactivated when a customer checks in.
