UnverifiedPM2.5激光散射传感器（如攀藤PMS系列）在高湿度环境（>70%RH）下会因水汽结露导致读数虚高，若卧室常开加湿器，应选带湿度补偿算法或明确标注抗湿的机型84% similarUnverifiedPM2.5检测的激光散射传感器需具备温湿度补偿，否则高湿环境（>70%）会把水汽误判为颗粒物，读数虚高2-3倍82% similarUnverified对温湿度敏感是电化学传感器的固有特性，高温高湿环境（如夏季梅雨）会使甲醛读数偏高，选购时应关注是否内置温湿度补偿算法74% similarUnverified湿度传感器长期使用会因灰尘、挥发性有机物污染导致零点漂移，Sensirion SHT系列支持通过在高湿环境(如密封盒放湿棉)静置数小时进行'再水合'恢复精度，廉价传感器则无此能力72% similarUnverified不建议仅凭湿度计上的甲醛/PM2.5等空气质量数值做判断，家用温湿度计集成的气体传感器多为VOC等效估算，精度极低不能替代专业检测71% similar
