This is not an exhaustive tutorial but it should explain roughly how I interfaced some “wirelessthings” wireless XRF temperature sensors and a “slice of radio” to my Raspberry Pi and logged data from them.

I will eventually get round to writing it properly.

To begin with I downloaded the lastest Raspian Wheezy, I know there are newer distributions available but I would stick with wheezy as they have changed the way to access the serial port.

Using Apple Pi Baker (a GUI SD card preparation application) I made the SD card ready for my Pi, put it in the Pi and booted with an ethernet cable plugged into my router.

SSH is installed by default on wheezy so I used fing to determine the Pi’s address on my network then used SSH with the user “pi” and password “raspberry”

I then updated the system and changed my password:
Sudo apt-get update
Sudo apt-get upgrade
And installed VNC Server, The instructions here https://www.raspberrypi.org/documentation/remote-access/vnc/ explain how to setup and install Tight VNC Server

You will need to setup your Pi to use the slice of radio, the instructions here give you an idea http://openmicros.org/index.php/articles/94-ciseco-product-documentation/raspberry-pi/283-setting-up-my-raspberry-pi you can ignore the SSH and minicom sections. although using minicom is a good way to see what the serial is doing without running any python scripts.

Well done you should now be able to talk to the sensors from your Pi! to configure the sensors download https://www.wirelessthings.net/launchpad and follow the instructions here https://www.wirelessthings.net/wireless-temperature-sensor to configure your sensors.

Finally you need to get the sensors logging I approximately followed the instructions here http://www.lourenco.eu/temperature/instructions.html just editing the python script to accept the message format of the wirelessthings sensors.

btw you can make your script executable using
chmod +x monitor.py and in the VNC instructions above it shows how to get a script to run at startup.

In theory your sensor data should now be appearing in the SQLITE DB from boot.

What you do with it all is now down to you, you can use SQL Lite Database Browser for GUI access to your DB, I installed apache2 with php and wrote a very simple page to pull data from the SQL.

I hope this helps
