Water leaks can be pernicious things. Even just a few drips per minute happening undetected inside a wall can cause major damage if left unrepaired for long enough. AquaPing is a new device that hopes to detect difficult-to-find water leaks with the aid of acoustic methods.
The AquaPing is a so-called “stand-off” sensor that is intended to detect leaks at a distance, even if they are inside a wall. No contact is needed with the plumbing itself. Instead, the device detects the broadband high-frequency noise created when water leaks from a pipe under pressure.
It’s a method that’s best suited to leaks from cracks or loose fittings. These generate a characteristic hiss that can be picked up with signal analysis even if the noise itself is obscured to human perception by other noises in the area. However, leaks like a hole in a gutter or a dripping rusted-out water tank are best found by other methods, as they don’t create this same signature noise.
The device will soon be launched on CrowdSupply as a purchasable product, however the project is fully open source for those eager to dive in themselves. We’ve featured some other really creative leak detectors before, too! Video after the break.
