基于nRF24L01的无线多点温度监测报警系统设计

Design of wireless multiposition temperature monitoring and alarm system based on nRF24L01

为了实现多点温度准确监测、无线传输与及时报警,设计了一种基于无线传输模块nRF24L01和数字温度传感器DS18B20相结合的温度监测报警系统。整个系统分为主机和从机,主机和从机通过STM32控制nRF24L01模块进行多频道通信,实现了多点温度监测。给出了整个系统硬件设计和软件程序的实现方法。通过在线测试,系统能够准确可靠地获得多点温度数据。该设计以低功耗、高性价比的设计思路解决了传统的有线布线繁琐、数据传输不可靠的问题,在农业、工业等领域具有很好的应用价值。

In order to realize the multiposition temperature accurate monitoring ,wireless transmission and alarm in time ,this paper designs a kind of wireless multiposition temperature monitoring and alarm system based on nRF 24L01 and DS18B20 .The whole system is divided into the master and the slave ,which makes multiposition temperature monitoring come true by the nRF24L01 module multi-channel communication controlled by STM32 .The whole system hardware design and software program realization method is presented in the design .After online tested ,the system is able to acquire multiposition temperature data correctly and reliably .By the low power dissipation and cost-effective design ideas ,the design solves the problem that the traditional routing is complex and the data transmission is unstable . Meanwhile ,it has a good application value in agriculture ,industry and other fields .
