I am looking for someone to make/prototype small unit that will detect movement in a room that will trigger a sound. Sound needs to be only heard by a dog. It needs to have an on and off switch so if I want to allow them into the room, then I can turn it off. Probably needs a training mode so it signals but doesn't impact them but that can happen after we figure out the details.

please solve this as soon as possible i need docomentation for this
