A new compact, five-channel sensor board from Information  System Technologies is  designed for real-time sensor-level signal processing in large wireless sensor network environments. The high-performance sensor board  provides has an onboard field programmable gate array (FPGa) and memory that allow for efficient implementation of flexible system structure and advanced signal-processing algorithms. An onboard radio provides added capability for self-localization. This technology overcomes the bandwidth and processing limitations in large wireless sensor networks, which may be deployed for real-time situation awareness and surveillance applications.

The sensor board can be interfaced with commercial Zigbee-based devices, e.g., motes. The system currently supports acoustic and seismic input signals, although it can be configured for other types of sensory inputs. Applications include acoustic localization and tracking of moving vehicles and gunshot detection, localization and classification. The system is suited for small fixed or moving sensor platforms, such as helmet-based systems.
