SainSmart LCD Keypad Shield for Arduino with Franzis Duemilanove Clone, DHT22 and Wireless Things XRF

The task is to use  an old Franzis Duemilanove Clone, a DHT22 and a Ciseco XRF to deliver LLAP (or the Language of the Internet of Things) via Radio (868 MHz) and to display Temperature and Humidity on the LCD.

The old Franzis Arduino Duemilanove came from one of their first starter learning kits. These kits were also sold in the UK at Maplin stores.

The Arduino Duemilanove (“2009”) was a microcontroller board based on the ATmega168 or ATmega328. It had a 14 digital input/output pins , 6 analog inputs, a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button.

DHT22 + Arduino Nano + Ciseco XRF

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.
