[0039] The sensor module includes a temperature and humidity sensor for monitoring the temperature and humidity of the hyperthermia fumigation instrument and an oxygen sensor for detecting the oxygen concentration of the hyperthermia fumigation instrument.

[0040] The 2-pin of the chip U1 is a data pin for data communication with the host device to transmit temperature and humidity data.
