description The utility model relates to a gaseous detection device, especially a gaseous detection device of environment trace. A gaseous detection device of environment trace, includes gas storehouse, upper cover plate, sensor, mainboard, sensor and mainboard are all fixed and form an airtight space on the gas storehouses, the sensor is gas sensor, including sulfur dioxide gas sensor, nitrogen dioxide gas sensor, ozone gas sensor, carbon monoxide gas sensor, be equipped with the air inlet on the gas storehouse, gas storehouse air inlet one end is connected with the air inlet of sensor, and terminal and mainboard connection are passed through to sensor gas outlet one end. The utility model discloses an environment trace ppb level gas sensor can survey hazardous gas in the environment, the low 1-2000ppb that reaches of its concentration measurable quantity. The detection demand is integrated gaseous module parameter together in assembleing near environment, is reducing detecting element simultaneously, has guaranteed to
