Final Report Providing the Design for Low-Cost Wireless Current Transducer and Electric Sensor Prototype

摘要

This report describes the design and development of a wireless current transducer and electric power sensor prototype. The prototype was developed for demonstration purposes. The report includes annotated schematics of the power sensor circuitry and the printed circuit board. The application program used to illustrate the functionality of the wireless sensors also is described in this document. The software was written to graphically display and archive the user-selectable measured electric properties, such as electric current, voltage, and real power, in near real-time as they are received from one or more wireless sensors. This prototype demonstrates the concept of wireless end-use power metering. By testing it in the building environment, the limitations that need to be overcome in a practical device for field deployment can be identified. It can also be used to demonstrate the concept to potential users of wireless end-use power meters as an aid in eliciting their input for the design of practical, field-deployable, wireless devices.
