Leak detector and sensor

A leak detection sensor comprising:

• a transducer, the transducer defining a mounting hole, the mounting hole configured to be repeatable, the transducer comprising
• a base, the base comprising a center,
• a piezoelectric layer, the piezoelectric layer deposited on a surface of the base, and
• a conductive layer, the conductive layer being an unbroken disc deposited on a surface of the piezoelectric layer;
• and
• at least two leads connected to the transducer and to a processing device, wherein only a first lead of the at least two leads is connected to the conductive layer,
• wherein the mounting hole is in the center of the base, a center of the piezoelectric layer, and a center of the conductive layer,
• wherein the transducer is coated in a non-conductive dampening material,
• wherein the leak detection sensor is a burst/tamper sensor and one of an array of sensors and is configured to be repurposed based at least on the mounting hole, and
• wherein the processing device is configured to
• continuously monitor a pipe to detect an urgent event, the urgent event comprising at least one of a pipe burst and a tamper event, and
• upon detection of the urgent event, wake a subsequent sensor in the array of sensors to monitor the leak event, the subsequent sensor configured to monitor the pipe on a wake/sleep basis.
