I need several sensors to quantify temperature, humidity, air speed, luminosty and maybe even air quality.

I'm hoping you plan to measure luminance rather than luminosity.

You're right, I translated the word directly into English -didn't know what luminosity was, so thanks!

As for the others, thanks for the answers. I'll have a look at digikey.

Any more suggestions?

Evening everyone.
So, after a long break I'm returning to Arduino with a project involving comfort management. I need several sensors to quantify temperature, humidity, air speed, luminosty and maybe even air quality.

First of all, I'm trying to do some market research to buy the ones that best suit the project needs. Which websites/distributors do you usually get your sensors at? I've taken a look at sparkfun, mouser, seeedstudio, bricogeek, cooking-hacks and parallax.
Thanks in advance, and I'll post in the near future describing the project in more detail.

You sure that isn't the size it should be? Because I'm getting the same compiled size.
466 bytes is under half a KB, just saying...

Thanks everyone for your answers! I'm going to take a look at the materials and sensors you mentioned.

@Grumpy_Mike: Takin' a look at your MIDI Footsteps strain gauges.
@PeterH: Good thinking, thanks for pointing the slippery problem out.
@DVDdoug: I'm in Europe. With any luck, there'll be shipping possibilities or deals just as good nearby.
@Sacman: Looking into these glass wall blocks...

Thanks again.
5  Using Arduino / Project Guidance / Interactive dance floor on: February 21, 2012, 12:25:57 pm
Good afternoon.

I'm looking into the feasability of an interactive dance floor, something that would look like this:

The floor itself needs to be quite resilient to support the weight of a number of people - how much weight can a LED handle?
I'm also curious about which sensors to use. I ruled out vibration and infrared sensors because of the lights and sounds inside a disco.

So, what are your thoughts? Doable? Too expensive/complex?

Is the main problem the Arduino board's speed or simply the fact that Bluetooth data isn't a continuous stream?
What about an X-Bee, or a radio receiver?

I don't know, people. I think it would give you more of a headache than stress relief. LED light is not the same as natural light.
