摘　　要：在气象监测、工农业生产、军事控制等领域,大气压力和温度是非常重要的物理参数。文中提出一种基于ST89C52单片机和BMP180传感器的高精度大气压力和温度无线监测系统。该系统采用STC89C52单片机作为核心控制元件,发射端通过BMP180大气压力传感器采集实时的压力与温度数据,再经过nRF2401射频模块发射数据,接收端通过nRF2401射频模块实时接收发射端发射的数据,经过STC89C52单片机进行数据处理,最后在LCD1602液晶上实时显示。经测试,该系统能对大气压力和温度进行实时的监测和报警,最大无线传输距离达到10 m,压力测试相对精度为±0.01 kPa,平均相对误差在0.008%左右。Atmospheric pressure and temperature are very important physical parameters in the fields of meteorological monitoring,industrial and agricultural production,military control,etc.A high precision atmospheric pressure and temperature wireless monitoring system based on ST89C52 single chip microcomputer and BMP180 sensor is proposed.The STC89C52 single chip microcomputer is taken as the core control component.The transmitting end collects real time pressure and temperature da ta by BMP180 atmospheric pressure sensor,and then transmits the data though nRF2401 radio frequency module.The receiving end receives the data transmitted by transmitting end through nRF2401 radio frequency module in real time,and then the data is processed by STC89C52 single chip microcomputer,and displayed on LCD1602 liquid crystal in real time.The testing results show that the system can monitor the atmospheric pressure and temperature in real time and give an alarm,its maximum wire less transmission distance is 10 m,its relative accuracy of the pressure testing is±0.01 kPa,and its average relative error is about 0.008%.
