Abstract
The sensor network described herein uses a distributed sigma-delta converter, where each of a plurality of sensor nodes includes a sigma-delta modulator communicatively coupled to a remotely located sigma-delta processor in a control hub. Each sensor node generates a serial bit stream representative of a sensor output signal. The control hub includes a plurality of signal processors, each of which receive and digitally process the serial bit stream wirelessly transmitted by a corresponding sensor node. A controller in the control hub analyzes the digital output from each signal processor to determine one or more characteristics of the sensor network.
