Having two or more Arduino boards be able to communicate with each other wirelessly over a distance opens lots of possibilities like remotely monitoring sensor data, controlling robots, home automation and the list goes on. A good, reliable and inexpensive solution is NRF24L01.

The NRF24L01+ is a newer version of the NRF24L01, capable of doing an extra 250kbps of on-air data rate while the one without “+” has only 1Mbps and 2Mbps. Both versions can be mixed together as long as 1 or 2 MBps is being used as the data rate.
