综合介绍或申报理由：
MP503型气体传感器是空气质量传感器。采用多层厚膜制造工艺，在微型Al2O3陶瓷基片上的两面分别形成加热器和金属氧化物半导体气敏层，用电极引线引出，经TO-5金属外壳封装而成。当环境空气中有被检测气体存在时空气质量传感器电导率发生变化，该气体的浓度越高，空气质量传感器的电导率就越高。采用简单的电路即可将这种电导率的变化转换为与气体浓度对应的输出信号。The MP503 gas sensor is an air quality sensor. Using a multi-layer thick film manufacturing process, a heater and a metal oxide semiconductor gas-sensitive layer are formed on both sides of a miniature Al2O3 ceramic substrate, which are led out by electrode leads and packaged by a TO-5 metal casing. When the detected gas exists in the ambient air, the conductivity of the air quality sensor changes. The higher the concentration of the gas, the higher the conductivity of the air quality sensor. A simple circuit can convert this change in conductivity into an output signal corresponding to the gas concentration.
