Arduino + Pachube = Web Connected Sensors!
Quick update before I zonk out… Yesterday I setup an account for Pachube and spent all night getting familiar with how it works. Pachube describes itself as a service that enables you to connect, tag and share real time sensor data from objects, devices, buildings and environments around the world. The key aim is to facilitate interaction between remote environments, both physical and virtual.
It also works with Arduino and Processing… hrmmmmm…..
As a “test” project, I set up two light sensors in my room. One is mounted on the wall, the other is taped to the window facing outside. The idea is to compare inside light levels to outside light levels and adjust for energy consumption. If the light level outside is equal or greater than inside, then perhaps I should open the blinds to let in more light… or maybe even go outside… *gasp*
The two light sensors are connected to an Arduino running the Standard Firmata. The Arduino is connected to a PC running a Processing sketch that sends the sensor data to Pachube. Nice and easy! I’ll post more details, code and a basic tutorial later… after I’ve slept… that way it *might* make sense.
Until then, here are some pictures and graphs. (yay graphs!) The two graphs are generated by Pachube and are fairly easy to customize. The higher the number, the less light is present. So, hopefully the Inside Light Sensor will stay a nice high number as I sleep… while the Outside Light Sensor should lower over the course of the day.

The graphs will continue to update as they receive more data from the sensors. It will be interesting to watch and compare the differences in the two graphs. More to come soon!
