该文以ATMEGA48单片机为核心控制单元、以NRF24L01射频收发芯片为无线信号的发送和接收单元,分别设计了发射系统和接收系统,实现了从发送端到接收端之间的信息传输。接收端配置有蜂鸣器,当接收到发送端发出的数据信息后,接收端会发出报警声,从而实现系统的智能搜索功能。 In this paper, ATMEGA48 microcontroller as the core control unit to NRF24L01 RF transceiver chip for the wireless signal sending and receiving unit, respectively, the launch of the transmitter and receiver system designed to achieve the transmission from the sender to the receiver between the transmission of information. The receiver is equipped with a buzzer. When receiving the data message sent by the sender, the receiver will send an alarm sound to realize the intelligent search function of the system.
