I'm sure everyone has seen those small digital angle meters with reported accuracy typically 0.1 or 0.2 degrees. I'm looking to design something that can have an accuracy of 0.05 degrees and I think perhaps the ADXL350 might be a good candidate.
My objective is to keep the BOM below $50 so that eliminates some of the really high accuracy devices available. I tried to search for designs like this but didn't come across any (surprisingly).
Is this the right part or is there something I missed? Perhaps using multiple of these mounted in different orientations could improve the accuracy?
Thanks in advance for any replies.
