A method and apparatus for providing power management for a device including a radar unit and an ad hoc network node are presented. The present invention involves various individual components of the device being turned on and off in various sequences in order to minimize power draw of the device. This involves starting individual components ahead of when they are required so they are fully functional when needed.

Power management for a radar system and ad hoc node device

Embodiments disclosed herein include a radar sensor device for detecting movement and velocity of external objects within or around a particular radar sensor field. The radar sensor field can use an array or cluster or radar sensors, including compact (portable by hand) radar sensors that function as network nodes within a wireless, low-energy ad hoc network. Radar sensor devices can use vibration as a means of communicating power status, functionality, and progress of installation of a particular radar unit. Such a vibration can be executed at a particular predefined cadence, rhythm, or other pattern, to indicate a powered-on state, active network connectivity, and other device states. Such a radar sensor device provides silent and non-visible status indication for quick and efficient deployment.
