Water Leakage Detection Solution by MEMS Vibration Sensor for Sustainable Smart Cities
ABSTRACT
In recent years, water leakages caused by the bursting of aging water pipes have become a social problem worldwide. To enable efficient maintenance of aging water supply infrastructure and help realize sustainable urban life, a water leakage detection technique by MEMS vibration sensor has been developed for the remote monitoring of water pipes using independently developed wireless vibration sensor terminals. This presentation describes the three measurement technologies that support the water leakage detection technique: low-power technology that enables a battery service life of five years; ultra-sensitive MEMS vibration sensors that can detect even the slightest water leakage; and a water leakage detection algorithm that can identify water leakages from a wide range of different environmental vibrations.
