Gas Sensor |
| 摘要 |
In order to prevent deterioration and a breakdown of a sensor element when the sensor element is activated in a state where liquid is attached thereto, and to remove the liquid in a short period of time with lower power consumption, there is provided a gas sensor including a first heating element and a second heating element that is formed around the periphery of the first heating element and has a wider forming area than the first heating element, and measuring a gas amount by heating the first heating element to a predetermined temperature, in which the second heating element is heated when the gas sensor is activated, and the first heating element is heated to the predetermined temperature after a heat value of the first heating element is restricted for a predetermined period of time. |
