| Summary: | 碩士 === 逢甲大學 === 自動控制工程學系 === 105 === In recent years, the technology of home security system is become mature, but in common family, a camera is usually only installed in the outer wall, if there are in-vaders want to incursion house, the probability of the device being destroyed is very high. In this study, we propose a home security system, combined with an Arduino Yún control board, a passive infrared sensor array, a GSM/GPRS gateway, and the webcam mounted on the servo motors. The disadvantage of the blind area have been improved by the passive infrared sensor array, and the optimum effect can be achieved with a minimum number of the sensors to be used, thereby reduce the cost of the system. When the PIR array detect human movement, it can determine the lo-cation of human using outputs of the PIR sensors. Arduino control board can trans-mits signals to the servo motor immediately, drive the webcam to the correct location of the intruder. We can watch the instant video streaming with network, and send the warning message to the user by email, and upload images to Dropbox. At the same time, send a text message (SMS) to the user by GSM/GPRS gateway, when user de-termines the home is under invasion by the invaders, he can informed and transfer the image to the police immediately, to arrest trespassers in time. In the future, this home security system can also be used in the mobile applications, to achieve the effect of integration, and cooperation with the police, to gain more prime time.
