These are a series of 2.4 GHz Radio modules that are all based on the Nordic Semiconductor module nRF24L01. The Nordic nRF 24L01 integrates a complete 2.4GHz RF transceiver, RF synthesizer, and Enhanced ShockBurst™ hardware protocol accelerator supporting a high-speed SPI interface for the application controller.
The low-power module with range about (60 meter or so)Transceiver is available on a board with Arduino interface and built-in Antenna. Having two or more Arduinos be able to communicate with each other wirelessly over a distance opens lots of possibilities:
Remote sensors for temperature, pressure, alarms, much more
Robot control and monitoring up to 85 meters
Remote control and monitoring of nearby or neighborhood buildings
Transceivers like these both send and receive data in ‘packets’ of several bytes at a time. There is built-in error correction and resending, and it is possible to have one unit communicate with up to 6 other similar units at the same time.
