ESP-8266-Based Indoor Localization System

Although the indoor positioning system (IPS) has advanced greatly in recent years, no solution has become standardized. Wi-Fi technology is the system that is utilized in many public settings, and the solution we suggest in this dissertation would not involve changing the infrastructure—rather, it would only need to be reused and improved. Considering the existing five-meter Global Positioning System (GPS) precision, this method is reasonably precise and low-cost. A motorized directional antenna prototype employing the signal strength of two ESP8266s is designed in this dissertation. These position readings are computed and displayed using an ESP8266 Wi-Fi enabled device and a micro controller. For Internet of Things applications, one of the most widely used devices is the WiFi serial transceiver module ESP8266. It includes readings from the module's Received Signal Strength Indicator. This study analyses the characteristically obtained Received Signal Strength Indicator readings using the ESP8266 WiFi serial transceiver module. The objective is to look into the possible future applications of the Received Signal Strength Indicator value as a separate, stand-alone parameter for use in a range of applications, especially in the Internet of Things domain. Understanding the characteristics of Received Signal Strength Indicator readings and how they might be used in a variety of other scenarios has been made possible by the findings.
