Design of Real-Time GPS Tracker Using ESP-8266 With Blynk Application

In this brief, a continuous Global Positioning System (GPS) tracker is designed with the help of the ESP-8266 Node-MCU board. In this project, we can find the location of missing girls and children. Also, with this product we can find their location by keeping this device in their bags/pockets or somewhere else. A framework is developed for Global Positioning System (GPS) to track and locate any vehicle. The GPS module receives signals continuously from the GPS satellites and used to calculate the latitude and longitude coordinates of the location of the device. The ESP-8266 board is connected to the GPS module and reads its latitude and longitude data. The ESP-8266 board is also connected to the internet via Wi-Fi and sends the latitude and longitude data to the Blynk cloud server using the Blynk library and the Blynk authentication token. The Blynk application installed on a smartphone is also connected to the Blynk cloud server via the internet. The Blynk application receives the latitude and longitude data from the Blynk cloud server and displays it on a virtual display widget.
