摘要
采用单总线数字温度传感器DS18B20,以无线射频单片机nRF9E5为核心,实现了多点无线温度采集系统。多个传感节点负责采集温度数据,并无线发送,中心节点通过nRF9E5接收数据后,将采集的温度信息上传上位机,并由LabVIEW软件平台对信号进行显示、分析、存储及报警等。该系统功耗低,测量精度高,界面友好,易于实现。
The multi-point wireless temperature acquisition system is presented based on single bus digital temperature sensor DS18B20 and wireless RF chip nRF9E5.Sensor nodes collecting temperature data,and wireless transmission,central node receiver data through nRF9E5,then collect temperature information upload PC by LabVIEW software platform.The signal display,analysis,storage and alarm is realized.The system is low power consumption,high measuring precision,friendly interface,and easy to realize.
