Indoor Human Detection and Monitoring System Using PIR Wireless Sensors Array

Abstract:

This paper presents a design and implementation of an efficient and low cost system for indoor monitoring of human intrusion. The system design is based on the use of already available pyroelectric infrared passive sensors (PIR) that are able to detect thermal perturbation caused by moving objects within their field of view (FOV). Our design uses the PIR sensors in the geometric context as binary detectors with adaptive threshold estimation. The combined field of view of three PIR detectors is modulated by a custom designed lens mask to estimate the bearing angle of the single human intrusion. The prototype is formed by a sensing module routed wirelessly to another host module to visualize processed raw data.
