Tracing Path with Arduino Uno using GPS and GPRS/GSM

When people visit a new place they forget the path through which they have traveled and faces problem in returning. This situation can create the security issues, especially with the small children. With the help of this paper the path can be traced. Thus, in order to trace the path we require a good quality and low price real time system. The purpose of this paper is to trace the path in real time using Google Map on mobile phone. Embedded system integrating Arduino Uno R3 microcontroller, Global Positioning System and Global System for Mobile Communication technology using Google Maps. To trace the path GPS sends the coordinate to the GSM modem through the Arduino Uno R3 microcontroller. Microcontroller acts as an interface between GPS receiver GPRS/GSM module. After receiving the location coordinates from GPS module, the co-ordinates values are sent to Android Mobile phone through Short Message Service. In this paper, the GSM model serves as the transmitter while the second GSM modem as mobile phone serves as receiver for the GPS location coordinate and displaying the co-ordinates values. After receiving the data, the path of the user can be viewed on Google Maps by clicking the Application (Map). It completes a cycle in 90 seconds and time to deliver the message depends on the network. This time constraints can be increased or decreased.
