含义
湿度传感器异常。净化器显示的环境湿度数值明显偏离实际值，或显示”---“无读数。
常见原因
- 湿度传感器敏感膜被灰尘覆盖影响响应
- 传感器长期处于高湿环境导致电容式感湿元件饱和失效
- 传感器排气孔被胶水或异物堵塞
- 传感器焊点虚焊或连接排线接触不良
- 传感器采样电路基准电压漂移
自助排查
- 用软毛刷轻轻清洁湿度传感器通气孔
- 将净化器置于正常湿度环境（40-60%RH）运行4小时，观察读数恢复
- 使用独立温湿度计对比——确认传感器偏差程度
- 检查传感器模块在主板上的连接
- 若读数始终偏差超过±20%RH且清洁无效，需更换湿度传感器
English
Meaning
Humidity sensor anomaly. The displayed humidity reading differs significantly from actual conditions, or shows ”---” with no data.
Common Causes
- Humidity sensor sensing membrane covered by dust, slowing response
- Capacitive humidity element saturated from prolonged exposure to very high humidity
- Sensor vent hole blocked by adhesive, debris, or foreign objects
- Loose solder joints or ribbon cable connection on the sensor module
- Reference voltage drift in the sensor sampling circuit
Self-Check Steps
- Gently clean the humidity sensor vent hole with a soft brush
- Place the purifier in a normal-humidity environment (40-60% RH) for 4 hours and observe if readings recover
- Compare with an independent hygrometer to quantify the deviation
- Check the sensor module connection on the main board
- If the reading deviates by more than ±20% RH after cleaning, replace the humidity sensor
