Air quality measuring device, air quality measurement methods and air quality measurement system

摘要

Air quality measuring device that can be realized at low cost measurement of [challenges] atmospheric environment, to provide air quality measurement systems and air quality measurement methods. Disposed SOLUTION: A casing 20, a filter 34 for absorbing the gas component to be detected, arranged in the casing between the filter and the intake port 22, I adhered to the surface of the piezoelectric vibrating element of the first second resonance frequency changes according to the mass of material is disposed between the mass sensor 2a of the first resonance frequency changes according to the mass of material, downstream of the filter, attached to the surface of the piezoelectric vibrating element of the second and a fan 42 and the mass sensor of 2b, is arranged downstream of the mass sensor of the second casing, to flow air toward the exhaust port 24 from the inlet port.
