Abstract

The General Packet Radio Service (GPRS) technology of Global Systems for Mobile (GSM) was used to study, evaluate and implement a remote data transmission system that connects to the Internet to remotely transfer data. The Telit GM862 GSM/GPRS module was used as the transceiver to send and receive data packets using the existing GSM network of Globe Telecom. A Web-server was set-up to receive and process the data sent by the remote system. As the data is received by the web server it is stored in its database which is ran by MySQL. Access, control and processing of data were implemented using PHP scripts. The data transfer was tested using a personal computer and was then tested using a microcontroller. The data transmission rate was determined by determining the roundtrip time from the client request and the server response. The remote data transmission system was interfaced to an existing data logger system for wind speed, wind direction, and atmospheric pressure. The reliability of real-time monitoring was implemented and evaluated.
