A nRF905?based wireless communication system working at 433 MHz is designed in this paper. The system con?sists of two modules:one is transmission module and the other is receiver module. The transmission module is composed of PIC16F877A MCU chip and nRF905 chip,and PIC controls nRF905 to perform transmission function. The receiver module is made up of MSP430 MCU chip and a nRF905 chip,in which MSP430 controls nRF905 to perform signal receiving. The system can be applied in the field of wireless meter reading and is of great importance to the living and the production. The paper de?scribes the design of hardware and software of the system in detail.
