 Bigger Bigger  Smaller Smaller  Reset Reset

I want to be able to monitor Temperature and Humidity using the Arduino board.  Can anyone suggest a Temperature sensor which will work nicely?  
or do I have to create a circuit to monitor temperature and pass the output to the Arduino board?

If I have to create a circuit can anyone suggest any beginner style temperature circuits?

Sparkfun has a combination humidity / temp. sensor.

A little pricy at 42$, but the advantage is that it is fully calibrated, something that can be difficult to do yourself.

Or you can just google "Arduino temperature sensor" = lots of info

The word you should look for is "thermistor".  Or, you could go for a digital version and get a DS18S20 temperature sensor that connects with I2C (the "wire" library): http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1230763968
