Hi, I work in an experimental biomechanics lab at Emory University and I am using a series of load cells (https://www.sparkfun.com/products/14727) and amplifiers (https://www.sparkfun.com/products/13879) to create a series of force sensitive pegs on a wall. We would like to be able to read out a force signal from each peg over time simultaneously. we are currently doing that using an arduino, but we would like to read out the signal from around 50-100 individual load cells simultaneously. Can you recommend any products or interfaces that will help us do this?
This board https://www.sparkfun.com/products/1524, coupled with your load cell, and this board https://www.sparkfun.com/products/15242; should allow you to tie up to 64 (I believe) instances.
That first link is broken, could you send another? And does the qwiic scale go in place of the amplifier?
Sorry, not sure what happened there. The first link was the QWIIC MUX so you can combine a number of scales together: https://www.sparkfun.com/products/16784
The Qwiic Scale (https://www.sparkfun.com/products/15242) does replace the HX711 amplifier. You can look a the hookup guide (https://learn.sparkfun.com/tutorials/qw … okup-guide) on how it works (and similarities to HX711).
