This document discuss about the development and working of a prototype of an AMR (Automatic Meter Reading) using Arduino board. The AMR is now a general term for all kind of meters that can read the data, store the reading and transmit the reading wirelessly on request to another device.There are already water-meters available which allow the interfacing of reed-switch. This project uses a reed-switch along with a rotating magnet to demonstrate the working of AMR.
