2.4GHz Wireless Transceiver nRF 24L01 (85 meter)

From the shop's description

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. Note: We have tested this module in Future Electronics (Arduino Egypt) site with one tranceiver indoors and the other one outdoors and the communication distance was more than 85 meters Features Power Supply: 3.3 v On-board integrated pcb antenna 100m Range at 250kbps Ultra low power consumption – months to years of battery lifetime 250kbps to 2Mbit Data Rate Auto Acknowledge & Auto Re-Transmit Multiceiver - 6 Data Pipes Software selectable channel from 2400MHz to 2525MHz (125 Selectable channels) ​ ​ ​​For nRF24L01 datasheet, click here Everything You Need to Know about the nRF24L01 ​ For nRF24L01-2.4GHz - HowTo and Arduino examples, click here
