Hello just picked up a Pi-B i have a pi-cam. I am interested in adding sensors to my pi to detect weather and relay the information to me and wunderground. I dont know how to solder but can learn or use a bread board not sure the exact terminology or equipment i will need. Many forums explain the layout of circuitry but no instructions on how to add the components to the board.
Thanks in advance

If you are using a breadboard you just insert the components into the breadboard and connect up the pins following the circuit diagram. For an example here is a Pi connected to an ATMega.
If you are just starting out I would say start with a bread board and learn from there as for the equipment you will need, well that all depends on the circuit you are creating. But basically you're going to need a breadboard, the components for the circuit you're creating, some Female to male jumper wire for connecting the Pi to the Breadboard and some male to male jumper wire for making connections on the breadboard (you can also use solid core wire for making your connections around the breadboard but I recommend getting some jumper wires for this as they come in different colours and it will help you navigate your way around your circuit., when all your connections use the same colour wire (if you're just cutting wire from a single spool) you can easily get lost in the wiring.
EDIT: I would also recommend you have a read of these links as they will give you the basics of breadboarding.

Thanks for the pictures, but we are going to need a little bit more information for you. Could you please link to the model of the temperature and humidity sensor you brought, it will help us better explain to you how to wire this thing up.
OK Red and Black are pretty much always Power, Red being positive voltage and Black being ground, the other two wires carry the information the sensor well senses. but the question now is 'Is that data digital or analog?' with the make and model of the sensor we should be able to figure that out.
But wait, theres more. A little CSI'ing later (using the included image manipulation tools on this machine) I can better read the label.
SDA and SCL are the give away signs that this is an i2c device. After a quick Google led me to Gordon Henderson's site (No not the MP, the guy who wrote WiringPi) https://projects.drogon.net/piface/ which states :-
The PiFace leaves all ports accessible on the Raspberry Pi itself, with the obvious exception of the GPIO port. It uses power and the SPI bus on the GPIO only. It does not make the other GPIO pins available for use.
Which kinda tells me that the PiFace can not be used directly to access i2c devices. So you are going to have to break out the breadboard and your jumper wires. But I will leave it at that for now as until I can get a better look at the temp/humid sensor.
