Abstract: This text is to introduce a portable wireless meter reading instrument which is made by microcontroller MSP430F149 and nRF401 and other components. The authors not only thought over the instrument should achieve the goal of “accurate, quick, overall”, but also took cognizance of the difficulty about wireless communication, at the same time, they gave consideration to the quality of the product which will face the market. They took their efforts to make it work reliably, cost moderately and be easy to operate and promote.
