A system having a user configurable and sizeable planar sensor pad having electrical circuits thereon, adjacent to a trough or groove formed in the sensor pad. These circuits are energized upon the application of a conductive fluid into the trough and once activated initiates a wireless communication device to transmit an alarm to a mobile device of the user, such as a smart phone, alerting the user of the detected fluid leak. The device may be self contained, operating on its own DC power source and may not require the use of a computer, a WI-Fi signal, or the internet.
