This is the summary of our weather here, collected over two years. Data was logged from a N23DQ 2.1.3 OS: 3.0.9 into MySQL as also seen in Periodic sending. The data gets send to a PHP script on a remote server that then makes graphs, overlays this onto a webcam picture, updates the MySQL database and sends the data also to Weather Underground. But Weather Underground does not give me overall mean temperatures, and does not log certain values, but samples more often, while I took samples every 5 minutes in my own data base. Discrepancies in the histogram and the WU data are explained through this. The peak value of 42 degrees would also have been achieved in full sun exposure. Continue reading Two Years Weather Summary

The Arduino Fio is a microcontroller board based on the ATmega328P and runs at 3.3V and 8 MHz. An XRF/ARF/XBee socket is available on the bottom of the board.
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 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.
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.
