数据采集问题，高手进来下啦

[凌晨27点]

在准备LabVIEW研究论文，刚刚接触，很多不懂的。。假如，我想做一个多功能仪器，比如测电压、电流还有温控湿控等等，问题来了，这些电压电流温度湿度信号怎么输入电脑啊？ 上网找了，说要数据采集卡，还是很模糊，谁给详细解释一下啊，谢谢了！！！

数据采集卡 就是采集信号

In simple words... 

电压、电流还有温控湿控... these are basically analogue signals of which the not in the format that PC could understand, thus, you need DAQ (Data Acquisition) Card(s) that does the ADC etc. converting the input analogue signals to the appropriate format the representation that PC understood...

Basically, they are the interfaces between the PC (software) and the transducers (acquiring data from the actual world).

but,where can i get the DAQ  Card?and how much?

Search NI.com or contact your local NI Office 😉

Or visit the DAQ Hardware site...
