Wireless Communication with accelerometer

Community Projects
1

Hello all,

I’m working on a project that requires an arduino mega to communicate with an accelerometer through wireless communications. I’ve never done anything like this before and was looking to get some insight. Was looking at the using something like the bluefruit ez link and board but was hoping to find something a little less expensive that would still work. The distance between the computer and the transmitter would be a couple inches at most. Any and all input would be greatly appreciated. Thank you ahead of time!

Accelerometers need an MCU of some sort to read out the data, before it can be sent by wireless.

Perhaps an analog accelerometer and an XBee ??

(substitute Accel for FSR)

The Nordic transceivers might have a similar analog capability, I don’t know.

or

with its ADC and some Arduino code?

PS: SFE does/used to sell these

XBee Pro at 2.4GHz might work… depending on path clearance. Sub-GHz is always better for low rate telemetry

You can use RF transmission to communicate wirelessly, to the Accelerometer. TO understand the interfacing between the two you should search like “accelerometer based gesture controlled robot”. You can find many, Two of which I am posting here which looks good:
