摘要
为实现特殊环境温度采集,设计了一种基于NRF24L01射频芯片的无线温度采集传输系统,选用DS18B20温度传感器,使用51单片机作为系统控制器,将温度值通过NRF24L01无线模块发送,接收系统通过NRF24L01接收温度值,并将接收数据在LCD1602液晶屏上显示,同时通过RS232串口发送到PC机。本文设计的无线温度采集系统具有硬件电路简单、设计成本低、功能稳定等优点。
In order to realize the temperature acquisition in the special environment, the paper designs a wireless temperature ac- quisition and transmission system based on the NRF24L01 RF chip. Taking the DS18B20 as temperature sensor and the 51 single chip microcomputer as the system controller, the system sends the temperature value by NRF24LO1 and receives it also by NRF24L01, then the temperature data is displayed on the LCD1602 screen, and at the same time, the temperature is sent to PC through the RS232 serial port. This system designed in this paper has the advantages of simple hardware circuit, low cost and stable function etc.
