Yes, you can repurpose your sensors.
Repurposing devices within the same organization
First you need to remove the physical device from it's current install location
Next you will need to un-map the device from the floor plan
Once complete you can rename and move the device to the new building and then map it to the new building's floor plan
The last step is physically installing the device in it's new location
Repurposing devices to another organization
Moving devices from one organization to another is not currently possible by users in the platform. A request will need to be made to Infogrid Support.
