A remote real time AMR (Automatic Meter Reading) system based on wireless sensor networks is presented in this paper. The useful remote AMR sensors were analyzed and efficient wireless network was suggested. The remote measurement system for water supply is taken as a typical example in experiments. The structure of system employs distributed structure based on wireless sensor networks, which consists of measure meters, sensor nodes, data collectors, server and wireless communication network. For a short distance transmission, the data collector collects data from the water meter sensors using the RF and ZigBee communication. For a long distance transmission, from the data collector to the server, system uses CDMA cellular network. The water meter data are received at the server through LAN using TCP/IP protocol. The proposed system have abroad application foreground in the real application field.
