E5 低

E5 - 飞利浦 空气净化器

中文

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

  1. 湿度传感器敏感膜被灰尘覆盖影响响应
  2. 传感器长期处于高湿环境导致电容式感湿元件饱和失效
  3. 传感器排气孔被胶水或异物堵塞
  4. 传感器焊点虚焊或连接排线接触不良
  5. 传感器采样电路基准电压漂移

自助排查

  1. 用软毛刷轻轻清洁湿度传感器通气孔
  2. 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
  3. 使用独立温湿度计对比——确认传感器偏差程度
  4. 检查传感器模块在主板上的连接
  5. 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

  1. Humidity sensor sensing membrane covered by dust, slowing response
  2. Capacitive humidity element saturated from prolonged exposure to very high humidity
  3. Sensor vent hole blocked by adhesive, debris, or foreign objects
  4. Loose solder joints or ribbon cable connection on the sensor module
  5. Reference voltage drift in the sensor sampling circuit

Self-Check Steps

  1. Gently clean the humidity sensor vent hole with a soft brush
  2. Place the purifier in a normal-humidity environment (40-60% RH) for 4 hours and observe if readings recover
  3. Compare with an independent hygrometer to quantify the deviation
  4. Check the sensor module connection on the main board
  5. If the reading deviates by more than ±20% RH after cleaning, replace the humidity sensor
