Use of Time-Variation Ultrasonic Signal and Multiple Sensors to Enhance the Sensing Reliability of an Embedded Surveillance System
碩士 === 輔仁大學 === 電機工程學系碩士班 === 102 === In this thesis we design and implement an embedded surveillance system by use of a time-variation ultrasonic coding signal with multiple pyroelectric infrared sensors (PIR) to detect an intruder in a home or a storehouse. The ultrasonic sensor module consists of...
