General question about adding sensors to Espruino

Hello,

I'm new to Espruino so please bear with me.
I'm thinking to buy Espruino, but I get confused a bit. I would like to attach a humidity + temp sensor. The question is where can I buy those and how can I attach them?

Looking for example on this page:
http://www.espruino.com/Project%204
it is written the following:
"Examples on how to get the temperature from a DS18B20 sensor are on our OneWire page." That is cool, but what about this "DS18B20 sensor"? Is it on the board already? If not, where can I buy it? Should I get also http://www.espruino.com/OneWire?

Another example is http://www.espruino.com/Stepper+Motors. Where can I get these?

Thanks,

Hello,
in the US take a look at Adafruit.
In the UK I've found Hobbytronics and in Germany (where I'm located in) the usual suspects are

• Conrad Electronik
  
• Reichelt
  
• Watterott Elektronik
  
• Exp Tech
  
  

Worldwide: Search for DS18B20 at ebay or for "DS18B20 Arduino" on google and you get a list of sources of supply for your country (with a lot of pictures and instructions to wire the sensor).

Maybe somebody can extend this list of mail order companies.

Greetings
Oliver

Hi,

Oliver - thanks! Yes, if others can suggest good places maybe post them here - I'd like to add a page which shows various suppliers.

In the UK there's also http://www.phenoptix.com/

DS18B20/OneWire : OneWire itself is a way of communicating (like SPI or I2C) and is built onto the board. It's the DS18B20 sensor that you need - as Oliver says you can easily get them on eBay - some of them look like transistors, but you'll want the ones that come with a long wire and a stainless steel end.

Looks like eBay is going to be the best option for local tidbits. I'm in Australia so if anyone has any suggestions for here that would be awesome.

In the UK I've used http://oomlout.co.uk/ before.

They were excellent, correcting my order for me when I'd made a mistake and not even charging me the difference.
