ABSTRACT

Internet of Things (IoT) is the fast growing technology that are prevalent in day-to- day life due to their improved use in ubiquity of smart mobile devices such as smartphones, tablets, notebooks, personal digital assistants (PDA), etc. It could be possible to create a digital world by using the main aim of the IoT enabled things (i.e.) "connected anywhere at any time”. Now days human or user activity detection is a major challenging task because detection and analyzing the user activity by using the surveillance camera and other external sensor is a tedious, time-consuming task and requires high hardware cost. The present study highlights the development of human activity detection system by using low cost Pyroelectric Infra-red (PIR) sensor and external Bluetooth Low Energy (BLE) with STM32F407VG microcontroller in IoT. The user activity’s signals are detected during week wise manner across various time periods by using LabVIEW toolkit installed in the department of CSE admin server which works within the certain BLE range. When compared the performance results between the proposed system and existing system for the average user activity detection, it was observed to be 88.75% and 83%, respectively.
