How do I connect 5 sensors via wireless or RF ?

I have 3 pressure sensors and two temperature sensors and would like to have the readings from these sensors to a central Arduino. How can I send the signal of these sensors via wireless RF or Bluetooth ? Should I use an Arduino Nano and a transmitter and receiver in each sensor? Or Bluetooth module can communicate 5 Arduino and read all the sensors ? How can I set this up?

Well, if you can't have an arduino wired to more than one sensor, then you'll have to have an arduino + communication (wifi, bluetooth or radio transmitter/transciever) for each sensor.

What (type of) sensors and which of them can be close to each other?
