user28176: I want to transmit some values from arduino uno to my phone using bluetooth.
Which sensor i can use?I want to see some options because i'm a little bit uncertain.Thanks to all which can give me an advice !  :)

user27157: It's not a sensor, its a module. A quite popular module is the HC-05. It's a very simple to use module with a lot of support by the community. Cheap and great for projects.
