Abstract:

This summary report describes the findings of a Phase I SBIR program to develop a batteryless and wireless sensor designed to monitor door and window openingsclosings. The sensor radiates a coded signal to a central processor unit which identifies the location of the entry and can time code the event. The sensor works by converting the mechanical energy available by a doorwindow movement to a dc voltage which powers an imbedded tone modulated oscillator. The program concentrated on the development of the most efficient means to convert the available mechanical energy into electrical energy, as well as a means to effectively radiate the alerting signal. Four different energy conversion sources were developed. Two receivers were also designed and developed for use with the sensors. The sensors were located both in the jamb and door knob. Installation studies, as well as experiments. were conducted to determine the range of the sensor signal which can be up to one mile. The practical range depends on the sensor location. Based on the highly successful conclusion of Phase I, it was decided to submit a Phase II proposal in concert with an experienced sensor manufacturer to exploit the commercial aspects of this sensor.
