A detection system and a humidity detection method for detecting a volatile organic compound are provided. The detection system comprises a device for introducing clean air and a controller, wherein the device for introducing clean air is connected with a test chamber; a test chamber sheath is sleeved outside the test chamber; the test chamber is provided with a temperature sensor for detecting the temperature in the test chamber, a high-temperature test exhaust device connected with a high-temperature exhaust pipeline of the test chamber, and a low-temperature test exhaust device connected with a low-temperature exhaust pipeline of the test chamber; a pipeline connecting the test chamber with the low-temperature test exhaust device is also provided with a dew point sensor for detecting dew point of the air in the low-temperature exhaust pipeline; and the temperature sensor and the dew point sensor are connected with the controller. The technical problem that the humidity sensor of the conventional detection system is easy to damage during high-temperature detection is effectively solved; and the detection system can perform low-temperature detection and high-temperature detection, has low maintenance cost and is convenient to use. |
