Design of Wireless IoT Sensor Node & Platform for Water Pipeline Leak Detection

Globally leakages in portable water supply lines amounts to be more than 40% with the costs of ~US$ 100 billion in revenue and has a major impact on economies. This implies that there is a need for systems to be developed to monitor pipeline leakages to avoid the water loss. Frequency signature of the hissing noise created during the water leaks, can be detected by acoustic sensors such as hydrophone to detect the water leak. In this work a hydrophone based IoT wireless sensor node and platform is presented for water pipe line leak detection. Leak detection is achieved by capturing acoustic signatures from an array of active hydrophones placed at regular intervals on the pipelines to pick up acoustic signature. Captured acoustic signatures are sent to the central server through the Wi-Fi network for post processing and leak detection.
