1. A leak detector comprising:

  • a sensor assembly including at least one sensor configured to sense acoustic signals; and

    at least one printed circuit board coupled to the sensor assembly and configured to support a processing device, the processing device comprising at least a processor, a storage module, the processor comprising at least a microcontroller unit (MCU) and a digital signal processor (DSP), the storage module comprising a database configured to store the acoustic signals from the sensor assembly;

    wherein the MCU is configured tocontinually receive the acoustic signals from the sensor assembly,wake the DSP at predetermined times based on a sensing schedule, andwake the DSP during a detected event, the detected event comprising at least one selected from the group of a large leak and a burst in a pipe;

    wherein the DSP is configured to remain in a sleep mode except when the MCU wakes the DSP from the sleep mode;

    wherein the processing device is configured to derive a probability that an event exists by comparing new acoustic signals to stored acoustic signals, the event comprising at least one selected from the group of a large leak and a burst in a pipe, wherein the stored acoustic signals comprise live data collected on a pipe network; and

    wherein the processing device is further configured to provide a probability indication, the probability indication expressed as a percentage of a likelihood that the event exists.
