responding to a setting instruction of the trigger threshold, and receiving a set value of the trigger distance;

and determining the trigger threshold according to the set value of the trigger distance.

6. The method of controlling a sensor according to any one of claims 1 to 3, further comprising, before the step of obtaining a first sample value of the sensor in response to a selection command of a calibration background noise value:

receiving a starting instruction of a proximity sensing function, and outputting first identification information of a calibration background noise value and second identification information of a default background noise value;

determining that a selection instruction of the calibration background noise value is received based on receiving an input instruction for the first identification information.

7. A control device for a sensor, comprising:

a memory having a computer program stored thereon;

a controller executing the computer program to implement the steps of the control method of the sensor according to any one of claims 1 to 6.

8. A cooking apparatus, characterized by comprising:

a sensor;

the control device of a sensor according to claim 7, wherein the control device of a sensor is connected to the sensor.

9. The cooking apparatus of claim 8, wherein the sensor is disposed on a key of the cooking apparatus or a panel of the cooking apparatus.

10. Cooking apparatus according to claim 8,

the sensor comprises an infrared sensor;

the cooking apparatus further includes: a function device connected with the control device of the sensor, the function device configured to determine that motion information is received, and switch from a first state to a second state.

11. The cooking apparatus according to any one of claims 8 to 10, wherein the cooking apparatus comprises: any one of a microwave oven, an oven, a steam box, a micro-steaming oven, a steaming oven and a micro-oven.
