My normal combination on the big-server side would be Apache + MySQL (or PostgreSQL), but on the RPi this seems to be absolute overkill. For data-logging operations I would not use the local system anyway (looking at MQTT as well as Remote MongoDB datastore via REST Webservices). After some poking around and reading up on the options I decided to go for the following combo: LightHTTPD + SQLite. Both are lightweight replacement of their fully-featured big-server counterparts (Apache HTTP & MySQL) and have very familiar configurations.

To connect 1-wire serial devices to the RPi I am using a DS9490R USB 1-wire adapter (rather than wiring I2C 1-Wire master components to GPIO I2C – which I might look at sometime down the track) Install packages sudo apt-get install owfs ow-shell Edit config file vim /etc/owfs.conf ! server: server = localhost:4304<br></br># USB device: DS9490<br></br>server: usb = all<br></br>######################### OWFS ##########################<br></br>mountpoint = /mnt/1wire<br></br>allow_other<br></br>####################### OWHTTPD #########################<br></br>http: port = 2121<br></br>####################### OWFTPD ##########################<br></br>ftp: port = 2120<br></br>####################### OWSERVER ########################<br></br>server: port = localhost:4304

With the Internet of Things slowly becoming mainstream the potential uses of this technology can also be seen in the Education sector. This blogpost is the first installment of a series of posts that highlights practical examples that can be used in teaching and training. Part 1 – Environmental Noise Monitoring Some of the skills taught in these projects are: Environmental science Citizen science (collaborative data gathering) Measurement / sensing Data visualisation Data comparison With WideNoise users can monitor the noise levels around them using an App downloadable from Android Market or Apple AppStore.
