A GSM - SMS - based wireless automatic meter reading system is introduced in this paper. It is more efficient than manual meter reading, and cheaper than automatic meter reading based on wireless sensor networks. It contains three parts: upper computer, lower computer and terminal. The upper computer and lower computer communicate by GSM SMS. The lower computer and terminal communicated by RS - 485. The wireless automatic meter reading process is finished efficiently and inexpensively.
