Abstract: Nonstandard wireless data communication is realized, based on the RF chip nRF2401 for the 2.4GHz ISM band. The main characteristics of nRF2401 are introduced. The hardware interface circuit between the +5V microchip AT89C51 and nRF2401 is designed to solve the problem of level conversion. The control process of software is introduced in detail. Actual operation indicates that the system can be easily controlled, it run steadily, and the bi-directional data transfer is realized.
