碩士 === 國立中興大學 === 電機工程學系所 === 105 === Pyroelectric infrared (PIR) sensors are low-cost, low-power sensors, which are widely used in energy saving systems and alarm systems. Currently, we have two approaches to detect the location of residents: terminal-based and non-terminal-based methods. The difference is whether the user needs to carry a terminal device. In this thesis, PIR is used to compose the non-terminal indoor localization system mounted on the ceiling. The PIR detection modules system (PDM) consists of two PIR modules. Object space is divided into discrete cells by using appropriate reference structure. After analyzing collected infrared signal of human, we can define the location of target. We consider the deployment of two modules with across their discrete cells to divide into smaller cells, which may lead to higher estimation accuracy. By changing the placement of modules and area of cells, we can observe the influence of different ratio between cells.
