"Pipe to Sense" aims to reduce the number of geophone sensors needed by attaching them to the floor heating pipes, commonly found in Korean apartments. Typically, geophone sensors were placed on floors to detect occupants by sensing vibrations induced by their footsteps. However, by attaching sensors to the pipes, it is anticipated that each sensor can effectively cover the area through which the pipes run.Â
Introduction
In state-of-the-art solutions, at least one geophone is required per room (approximately one per 2 meters). However, this study aims to detect floor vibrations more effectively by placing geophones on the floor heating pipes, which are typically located under the sink.
Background
Boiler Piping Diagram.
The boiler pipes extend from the distributor, traversing each room.

Preliminary Evaluation
Experimental Setup. A geophone was attached to the pipe leading to the bedroom, and the occupant was instructed to walk in the room, taking one step every three seconds.
Experimental Result.
Future Considerations
How can we filter out various noises from pipes (e.g., water flow)?
Do the detected signals contain enough information for occupant identification?
Can the sensors be designed to withstand the heat from the pipes?
How far away can the system effectively detect vibrations?
How much more effective is this method compared to existing research?
