Abstract:
An imbedded Internet sensor system for protecting real property from the consequences of subterranean chemical pollution. The system provides real time monitoring of the first occurrence of contaminants in the subsurface of a property. An onsite processor controls a local network of sensors and a communication device relays the data to a remotely located database. The local network of sensor are made up of multiple acoustic wave sensors differentiated by sensor coatings configured into a sensor array. As a vapor contaminant passes across the surface of the surface acoustic wave sensor crystals, a shift is caused in the frequency of the acoustic wave. The shift is translated into an electronic signal that is communicated to the onsite processor, which in turn communicates the signal in the form of electronic data to a remote facility wherein remedial measures may be dispatched and appropriate parties notified. The method of dispatch and notification is provided by a Web site system accessible through the Internet. The system is provided as part of a pollution detection and notification service for which a customer pays a subscription fee.
