Most sensors need to be connected to an Arduino by wires. The Arduino can send data elsewhere, wirelessly.

First, get a sensor that can send wireless information.
Second, get a receiver that can listen to that frequency
third, listen to that frequency and log the data sent.

most of use a sensor that is wired, and then have the Arduino the sensor is connected to, connect to a transmitter and that sends the data to a second Arduino that is connected to a receiver in some other place.
