In this Demo, we present the design and implementation of a novel human localization and tracking system based on pyroelectric infrared(PIR) sensors. It is a new approach to setup several low-cost sensors to improve the simplicity of deployment. We first present a novel design in mechanical architecture, circuit board and sensors which enables our PIR sensor based system to detect the moving objects and track human beings in real time. Different from the previous work which only adopts binary output, we further explore the usage of analog signals from the sensors. This improvement is beneficial to accurate estimation of the distance between the device and human body. We have implemented several prototypes for evaluation and demonstration. According to the experimental results, our system can achieve an accuracy of 0.113m in an area of 12m * 6m.
