Water leak detection using pressure sensing

This system detects water leaks in a building's plumbing by measuring water pressure at a single point using just one sensor. It doesn't track water flow; instead, it looks for unusual, non-repeating pressure changes, like a sudden turbulence in the pressure readings, to identify a leak.

Why it matters: Filed before low-power microcontrollers made real-time frequency analysis practical on-device. This advancement makes the complex signal processing described in the claims more feasible for embedded systems today.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: ModeratePressure sensor, processor, software logic for analysis
