采用超细SnO2粉体为材料基体，MQ-Y1元件生产工艺制成超细CO元件。在考察了工作温度、选择性、灵敏度、稳定性、响应及恢复时间等器件参数后认为，此元件可以在稍高于室温条件（25～30℃）下工作，是一种具有重要开发应用前途的气敏元件。
Using ultra-fine SnO2 powder as the material matrix, MQ-Y1 component manufacturing process made of ultra-fine CO components. After examining device parameters such as working temperature, selectivity, sensitivity, stability, response and recovery time, it is considered that this device can work slightly above room temperature (25-30 ° C) and is an important development and application prospect Gas sensor.
