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The NRF24L01+ is a newer version of the NRF24L01, capable of doing an extra 250kbps of on-air data rate while the one without “+” has only 1Mbps and 2Mbps.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.

The RF-Nano module is a compact, affordable module that combines an NRF24L01 wireless transceiver with an Arduino-compatible microcontroller. Using the NRF24L01 protocol, the RF-Nano operates on the 2.4 GHz band, making it a practical choice for creating simple, low-power wireless networks. This module is popular among hobbyists and engineers for tasks like home automation, remote control applications, and IoT sensor networks. It’s especially suited for applications where simple, secure data sharing between sensors or remote control devices is required and where a compact, low-cost solution is preferred.
