Abstract

There is provided a sensor node arrangement for a leakage event detection comprising two or more electrode elements from which at least one includes material with a different standard reduction potential than at least other one of the two or more electrodes, and electrolyte salt material. Upon a leakage event, the electrolyte salt is configured to cause a salt-bridge over the two or more electrode elements. The salt bridge and the electrode elements are configured to form an electrochemical cell. Sensor node electronics is configured to detect the leakage event from electric power generated by the electrochemical cell.
