无线温度监测装置的设计

Wireless Temperature Monitoring Device design based on MCU

无线温度监测技术在环境保护、科学研究和现代工农业领域有着广泛的应用。针对某些特殊的测温环境,比如森林、油罐等,设计了一款无线温度监测装置,能够实时检测两路温度并无线传送到接收端显示。系统主要选用STC89C52单片机作为处理器、DS18B20作为温度传感器、n RF2401作为射频无线收发芯片、LCD1602作为液晶显示器。DS18B20采集节点温度,STC89C52处理温度数据后使用n RF2401无线发送,接收端接收数据并由LCD1602进行显示。该系统具有两路温度实时检测、操作简便、准确度高、价格便宜等特点。

Wireless temperature monitoring technology has been widely used in the field of environmental protection, scientific research, modern industrial and agricultural. In view of some special environment, such as forest, oil tank, designed a wireless temperature monitoring device which can detect two ways temperaturereal-timely and transmit data to the receiver. Designation chooses STC89C52 single chip as processor, DS18B20 as temperature sensor, n RF2401 as wireless transceiver chip, LCD1602 as display. DS18B20 collects temperature of node A and B; n RF2401 wireless transmits data to receiver after STC89C52 processes and LCD1602 displays the detected temperature. The system has the characteristics of real-time detection, simple operation, high accuracy and low cost.
