Zeng Chui-shen · Automation and Instrumentation · 2009
For the absence of civilian infrasonic signal collecting system, a system was designed and realized with low cost. The infrasonic signal is collected by professional infrasonic sensor firstly. And then it is processed in turn by conditioning circuits, A/D conversion circuit, serial communication between micro-controller unit and personal computer. Finally, the signal can be displayed on PC. At the same time, the signal can be analyzed with software on PC.
