Cameron's Data Logger

Page history last edited by camerons 13 years, 11 months ago

My data logger is a multimeter that stores voltages with floating point precision and records the time it took them. It outputs this to the serial port for a program like matlab to use and plot. The time intervals and number of samples it takes can be adjusted at will. When you press the button it begins sampling until it takes the number of data samples you wanted. After it collects this number of samples it immediately outputs them to the serial port and goes into a waiting state until you press the button again.

Here is a video of my data logger in action.
