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 microcontroller unit (MCU) and a digital signal processor (DSP);
wherein the MCU is configured to continually receive acoustic signals from the sensor assembly; and
wherein the DSP is configured to remain in a sleep mode except when the MCU wakes the DSP from the sleep mode at predetermined times.

21. A method comprising:
-
placing a digital signal processor (DSP) in a sleep mode, the DSP being incorporated in a leak detector; determining whether a host-initiated request is received from a host and awakening the DSP when the host-initiated request is received; determining whether an urgent event related to a leak in a water main has been detected by a microcontroller unit (MCU) and awakening the DSP when the urgent event is detected; and enabling the DSP to analyze acoustic signals when awakened. - View Dependent Claims (22, 23, 24, 25, 26)
