Sensors to use with arduino

Using Arduino Sensors
1

For a project I am using a temperature, motion and moisture sensor. So can anyone give me a link to sensors that arduino can support or atleast a model number.
Thanks

Can you tell more about the measurement range:

  • temp: min temp - max temp - responsiveness
  • motion: what kind of movement at what distance
  • moisture: humidity or waterlevel or wed linnen?

For temperature - DS18B20 is an often used one (also available in a watertight encapsulation) - http://arduino-direct.com/sunshop/index.php?l=product_detail&p=151
For motion - PIR sensor ?
For moisture - metal strips self made?
