基于RF905模块和DS18B20的多点温度测量系统

Multi-channel temperature detecting system by DS18B20 based on RF905 module

介绍了由ATMEGA8A单片机、RF905无线收发模块和DS18B20温度传感器组成的多点温度测量系统,并详细说明了其硬件组成和软件设计方法。该系统的原理是:通过ATMEGA8A采集各点温度传感器DS18B20的数据,数据经过收集和初步处理后,在本机显示的同时,通过无线发射模块RF905发送至上位机,通过ATMEGA8A的SPI接口与RF905交换数据。实验结果表明,多点温度测量系统运行情况良好,具有较高的工程应用价值。

This paper introduces the temperature detecting system based on ATMEGA8A, RF905 module, DS18B20 temperature sensor and its hardware and software designing has detailed explanation and instruction. ATMEGA8A collects data on DS18B20, after data collection and processing, the data transmits through the RFg05 module. ATMEGA8A communicates with RF905 by SPI. The main charac- teristics of this system is used the RF905 wireless transceiver modules to transmit and receive data. The temperature detecting system runs well in practial operation process and is valuable in project application.
