Load cell for use in measuring isometric strength

Hey everyone,

I have spent a good bit of time scouring the board and looking through the posts but haven’t found an answer to my question. This could be due to my lack of knowledge around the subject so if it has been said before i would appreciate being pointed to it.

I work in sports and we do a lot of testing around various measures of isometric strength. I am looking for a way to set up a load cell so that I can get a csv file with tests sampled at 500-1k Hz. I would then use excel or R to calculate impulse, peak force, etc.

My question is what would those here with experience suggest is the best approach to doing this? I have listed below what i purchased to begin the learning process. Any feedback on what to use (python or Arduino or other?) and how to set it up would be greatly appreciated.

Hi,

a) The products you select can certainly fit your needs.
b) Using the Arduino and processing the data to a CSV file can be done, but it will require programming and research.
We would suggest you to use our blog article and code sample to use process the data from the load cell and send them over the serial port.
You will then need to use these data and save them in a CSV file.

This is a guide on how to save data from Arduino to a CSV file using Processing. This is a good starting point, but please note that we have not tested this process specifically.

Please don’t hesitate if you have any questions.
