The balloon itself usually contains devices to measure temperature, pressure and humidity.
Weather balloons typically carry a thermometer (to measure air temperature), a psychrometer (to measure humidity), a barometer (to measure air pressure) and a transmitter (to send the information through radio waves to equipment at the ground so we will know what the instruments are measuring up in the air)
The pressure of the air inside it. The higher the balloon rises, the lower the outside air-pressure. With less pressure outside, the balloon expands because of the pressure of the air inside it. Eventually, the balloon bursts, and scientists recover the instruments when they fall to earth.

Radiosonde is the general term.
The balloon itself usually contains devices to measure temperature, pressure and humidity.
A weather balloon gathers information on temperature, atmospheric pressure, humidity, and wind speed.

on a pressure meter it has no effect
there is no unit. Basically they track the balloon over a day and measure the speed it travelled to find wind speed.
As you rise in elevation, the pressure around you decreases. This lower pressure would cause the balloon to expand, and burst if it was inflated to much originally. By starting it off only partly filled, it will expand to a normal size and not explode.
Yes, it does, due to the decreasing pressure at higher altitudes.
A millibar is a unit of pressure most commonly used to measure atmospheric pressure.
