MicroPhonon careers

Acoustic leak detection has, until now, never been applied to automated home or building monitoring due to complexity and cost. MicroPhonon has solved these problems and developed an ultrasonic water leak sensor with these advantages:

* Completely automated for integration into a smart home or building product line.

* Signal processing at the edge; no audio streamed to cloud.

* Stand-off detection.

High-frequency acoustics are emitted by pressurized water as it escapes from cracked or leaking plumbing. Acoustic signals can travel a significant distance in air and be detected by a remote sensor.

This technology overcomes the shortcomings of available water leak sensors. There is no need to retrofit plumbing for inline smart meters, which are not sensitive to very low flow rates. Unlike contact water sensors, ultrasonic leak detection is effective throughout the building structure – including attics and crawl spaces where pooling of water is difficult to identify and access.
