I've ordered ADXL377 that can sense up to +/-200g. I will be measuring up to 10g. Can I hope for +/-0.5g accuracy?
Have you tried entering into your favorite search engine the words "adxl377 datasheet", to view the result set?
If you did you'd find this document: https://www.analog.com/media/en/technical-documentation/data-sheets/ADXL377.pdf, which should answer your question.
What I do, before ordering a part is:
A) find the product data sheet and read it.
B) find out if their is a Arduino library already made for the product.
Using those two pieces of info, I'll make my decision on the part before it arrives and I find out the part will not work.
As a note, B does not stop me from ordering the product, it lets me know, I'll have more work to do to get it going.
Thank you for the reply and a tip. I managed to switch the orders with ADXL326...
transducers do not function well in their bottom 1 or 2 percent. you should not put your full faith in data below 10% of stated range
transducer industry standard behavior is to make gages so the accuracy is consistent 20 percent beyond the stated range. a 10 g accelerometer is a reliable and accurate 12 g accelerometer
accelerometers typically survive an overload at 200 percent, so a 10 g accelerometer should survive 20 gs
