Description

Description:

This reference design demonstrates the board through which FFT of the vibration data can be sent out to another device using either Bluetooth® low energy or Sub-1 GHz wireless protocols. The low-power usage and wireless capabilities of this subsystem enables it to run on a single coin cell battery, which allows for the device to be small, inexpensive, and placed in difficult-to-reach locations. These features makes this design an ideal alternative to both expensive maintenance that could have been preventatively avoided as well as larger, more expensive monitors that require a wired connection
