WATER LEAK SENSOR AND WATER LEAK SENSING METHOD USING THE SAME

摘要

The present invention relates to a water leakage sensor to sense a water leakage and a water leakage sensing method by analyzing frequency areas of elastic waves caused by the leakage of water. The water leakage sensor comprises: a sensor unit to collect data on leakages based on the elastic waves; a converting unit to convert the data on the leakages, outputted from the sensor unit, into digital signals; a processing unit to determine whether there is a leakage by analyzing the digital signals inputted from the converting unit in the corresponding frequency areas; and a communication unit to transmit information about whether there is a leakage, inputted by the processing unit, to an external communications device. As such, in accordance with the present invention, whether a leakage is present is able to easily be checked using the elastic waves.
