Here we will combine an Arduino Nano, a DHT22 and a Ciseco XRF to deliver LLAP (or the Language of the Internet of Things) via Radio (868 MHz).
The Ciseco XRF is a wireless node. It is low powered and XBee shaped and has a RF serial data module. Operates in the ISM bands (868 to 915 MHz). It can be programmed over the air with a SRF – USB Stick or a Voyager+, as well as directly to the board’s serial or SPI pins with an FTDI breakout board.
The RFu – 328/SRF is an Arduino compatible wireless node.It’s equipped with a 16Mhz Atmel ATMega 328P preloaded with the Arduino Uno bootloader. It can be programmed over the air as well as directly to the board’s serial or SPI pins with an FTDI breakout board.
The SRF shield is a digital electronics development board. It’s a plug and play add-on for all Arduino style prototyping boards with Ciseco‘s SRF wireless module. Essentially it adds radio capabilities to the Arduino Uno Rev 3 board.
