zurienkhalid WROTE:actually i'm not familiar with electronic device...but for my final project i have to use electronic device..i'm networking student so really need help to build this for my final project..because may supervisor want use arduino to build wireless monitoring for temperature room...and i also need detail listing device..so please help...
the same thing i will tell you, pls start with basic first, especially for arduino beginners.
Some suggestion for you, LM35 is quite easy to use and its coding can easily get online.
The most basic things u nid to know now is how to connect it with arduino and give simple output if temperature more than 30 degree for example.
Following link might help, abit advance but is good if you can understand it

by hook or by crook, do it step by step.
