HUMIDITY SENSOR DIAGNOSTIC METHOD USING CONDENSATION CLEARING HEATER |
| 摘要 |
A diagnostic method for a capacitive humidity sensor comprising a heater, and a capacitance-sensing element that individually indentifies heater, temperature-sensing element, or capacitance-sensing element degradation. By this method, individual elements of the sensor may be replaced or compensated for to allow for further operation. |
