This paper presents the design and implementation of a secure low cost Automatic Meter Reading (AMR) system that calculates and transmits the total electrical energy consumption to main server using General Packet Radio Service (GPRS) technology provided by GSM networks. The proposed AMR system consists of three main parts: Accurate digital meter, a transmission facility and the billing server. To make affordable AMR system a low cost off-the-shelf materials are used. Successful demonstration of the system prototype has made it possible to be implemented in the Kingdom of Bahrain and other Middle East countries on a larger scale for meter reading applications.
