PROBLEM TO BE SOLVED: To provide such a radiosonde that communication means for communicating with an external device in order to change a frequency to be set in the radiosonde is formed so as to be able to contribute to weight reduction of the radiosonde, or stabilization of an adjustment test or the like.SOLUTION: A radiosonde for transmitting by radio via a communication part, measurement data measured by various sensors including a temperature sensor, has a frequency control part for changing a communication frequency, and a radiosonde side infrared communication part for allowing communication between the frequency control part and an external adjusting device by an infrared communication system. |
