【摘要】 设计了一种基于单片机ADuC845和PTR2000的无线数据采集系统,该系统充分利用ADuC845单片机的片上资源,特别是两个多通道且皆可达到24位分辨率的A/D转换器。它对外部模拟信号温度、湿度、压力通过传感器进行输入、放大、滤波后送入A/D转换器。通过对寄存器的合理配置,得到稳定的输出值,在数码上显示输出。最终通过PTR2000将处理后的数据发送到PC机上。更多还原

【Abstract】 The wireless data acquisition system based on ADuC845 and PTR2000 is designed.The system takes full advantage of ADuC845.Especially ADuC845 has two multichannel A/D converters which can reach 24 bit high resolution.The external analog signals of temperature,humidity and pressure can be input by the sensor,and then amplified and filtered into the A/D converter.The design allocates the register to get a stable output which can be displayed digitally.Finally,the processing data can be sent to PC by PTR2000.更多还原
