nRF24L01 2.4GHz Radio/Wireless Transceivers How-To


nRF24L01 2.4GHz Radio/Wireless Transceivers How-To


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 from 50 feet to 2000 feet distances
  • Remote control and monitoring of nearby or neighborhood buildings
  • Autonomous vehicles of all kinds

These are a series of 2.4 GHz Radio modules that are all based on the Nordic Semiconductor nRF24L01+ chip. (Details) The Nordic nRF24L01+ integrates a complete 2.4GHz RF transceiver, RF synthesizer, and baseband logic including the Enhanced ShockBurst™ hardware protocol accelerator supporting a high-speed SPI interface for the application controller. The low-power short-range (200 feet or so)Transceiver is available on a board with Arduino interface and built-in Antenna for less than $3! See it here.
