It is very simple to send data values from the accelerometer using the NRF24L01, but first you have to get all the project parts working individually, and make sure that you understand each part. One place to start would be the NRF24L01 tutorial on this web site.
It is not a good idea to arbitrarily map raw data before sending it to be processed.
I would recommend to use the HC-12 instead of the NRF24L01. It is much, much simpler to use.
