Person Location Tracking Using Global Positioning System and ESP8266 with Internet of Things

This paper explores the idea of locating the student’s location within the organization/institute. This is done by using a GPS-based receiver modem attached to ID card of student and using a SQL coded database. Initially, the system is provided with all the coordinates of the places within organization/institute, and these coordinates (latitude, longitude and altitude) are stored in a lookup table (LUT) in the database. When the student with the GPS receiver roams inside the campus, his coordinates are recorded by the GPS modem and sent to the database via Internet (cellular/Wi-Fi network). This coordinates are then compared with the coordinates in the LUT; if the coordinates are matched with any of the contents in LUT, then the system identifies this and knows the location of student; otherwise, the student is considered as out of campus. Any authorized person can access this data, i.e., students’ location at any time by either Web site or the application provided to the person by entering the unique ID number of the person who is to be tracked. Programming the NodeMCU has been developed in C environment with a self-made SQL database and person location data transfer to Internet of things using ThingSpeak software. This ThingSpeak software is used for the development of application.
