Nilima Zade et al., International Journal of Advanced Trends in Computer Science and Engineering, 10(1), January – February 2021, 417 - 422 417 ABSTRACT The development of surveillance systems for indoor and outdoor environments using currently available wireless sensor technology without violating privacy issues is a challenging task. Passive Infrared (PIR) detectors are suitable for such systems provided solutions to the technical limitations are implemented. In the proposed work, the development of a human tracking system using analogue PIR detectors and currently available wireless sensor technology is presented. Performance is evaluated by conducting real-time tests in different environmental scenarios. Analysis of experimental results of human sensing signals indicates that performance is affected by environmental parameters. These findings will be helpful for the researchers while implementing a real-time system in the field. Keywords: Passive Infrared Detectors, Target Tracking, Wireless Sensor Networks, Surveillance System. 1. INTRODUCTION Continuous monitoring of human being in indoor and outdoor environment without violating privacy issue is very important and challenging task in smart surveillance [1]. Developing cost effective, efficient system with the available off the shelf detectors for non-military applications is very difficult task. Active detectors such as visual camera, ultrasonic sensors, radar, microwave sensors, smart devices enabled with GPS technology provides accuracy in tracking with the trade off in increased power consumption and processing complexity [2]. The use of visual camera demands more battery power, processing power and large bandwidth for long distance communication. Passive detectors such as Passive Infrared sensors (PIR) can be used when optimization of power consumption and processing complexity is major objective to be achieved than the precise tracking accuracy. The current research is extension of the work [3] using analogue PIR sensor. The research presented here is the analysis of analogue PIR sensor performance in tracking application with indoor and outdoor environment. The objective is to test and compare analogue and digital PIR sensor performance when used in target tracking application in indoor and outdoor environment. Issues and challenges encountered and its probable solutions developed while implementing target tracking WSN are presented. The rest of the paper is organized as follows. Related work is described in section 2. Experimental setup, design and implementation is explained in section 3. In section 4 results along with analysis is mentioned. Conclusion is stated in section 5. 2. RELATED WORK In [4], [5], authors presented indoor localization using machine learning technologies based on the single analogue PIR sensor output. In [6], author proposed PIR based indoor localization using overlapped sensing area due to multiple nodes. In [7], author proposed geometric algebra approach using geographic sensor network for indoor localization. In [8], author used the multiple overlap Fields of Vision (FOV) of nodes with analogue PIR sensor. Most of localization techniques developed using passive sensor needs high processing power which leads to the restriction on utilization of these technique to indoor localization only. In [9,10] developed a system for outdoor localization using multiple analogue PIR sensor. To meet the requirement of high power, solar powered batteries are installed. The application specific analogue hardware implementations are not flexible, so are difficult to adopt as implementation for generalized application to outdoor environment. In [11] target tracking with binary PIR sensor is presented. In the previous work presented in [12,13], issues and challenges while implementing tracking system with binary PIR sensor has been presented. Researchers significant contribution indicates that such implementations are application specific and has scope in the field. 3. EXPERIMENTAL SETUP This research aims to test analogue PIR sensor for motion detection in indoor and outdoor environment.
