[0023] Furthermore, the sensor module 4 includes: a gas sensor 41, which is externally mounted at the air inlet 11 of the cabin 1. The traditional method is to build the sensor into the cabin 1. When conducting tests, the high temperature in the cabin makes it impossible for the sensor to work normally, and thus it is impossible to achieve automatic fire extinguishing, power off and other operations. The external gas sensor will not be affected by the temperature in the cabin, thereby ensuring the safety of the test.
[0024] Furthermore, it also includes: a condensation module 5, which is arranged at the gas outlet end of the suction pump 2, and is used to condense water vapor in the gas sucked out by the suction pump 2.
[0025] Furthermore, the condensation module 5 comprises: a condenser 51 and a drainage pump 52 . The condenser 51 is connected to the suction pump 2 and the drainage pump 52 respectively. The water condensed by the condenser 51 is discharged through the drainage pump 52 .

[0028] According to another embodiment of the utility model, an environmental chamber is provided, including an environmental chamber gas alarm system.
[0029] When using the environmental chamber for testing, the high-temperature gas generated in the chamber will be discharged from the exhaust port 12 of the chamber body 1. The high-temperature gas will be cooled by the air-cooled radiator, sucked out by the suction pump 2, and then passed through the condenser 51 to condense the water vapor in the gas, which will be discharged by the drainage pump 52. Finally, the gas passes through the three-way valve 6, and then passes through the flow meter 7 and the gas sensor 41 in sequence, and circulates into the air inlet 11 of the chamber body 1 to perform gas circulation.
