# Cheap alternative to an accelerometer [closed]

I am designing a very simple device, which absolutely needs to be inexpensive, total BOM cost < $1.00 including the MCU (at 10k+ units). This device would benefit from knowing its orientation, which could be binary - vertical / non-vertical. I do not need the granularity of an accelerometer just a reliable way to determine single axis position in a binary format. After a google search, I am still empty handed, I have only been able to find full blown accelerometers which start at around$0.40. I was hoping to get something fo \$0.10 or less (at quantity). I would love to get some input on any options for this.

• Um, can you tell me where you are finding accelerometers for only 40 cents? :) – bitsmack Mar 2 '17 at 6:36
