and S121, when the rotating speed of the air conditioner fan is larger than a preset first rotating speed threshold value, controlling the dust sensor to operate in a high-speed operation mode.
Optionally, step S12 is specifically executed by step S122:
and S122, when the rotating speed of the air conditioner fan is less than or equal to a preset second rotating speed threshold value, controlling the dust sensor to operate in a low-speed operation mode.
By presetting the first rotating speed threshold value and the second rotating speed threshold value, when the air conditioner fan runs, the rotating speed of the air conditioner fan is obtained and compared with the two preset threshold values. When the rotating speed of the air conditioner fan is larger than a preset first rotating speed threshold value, the rotating speed of the air conditioner fan is larger, so that the operation mode of the dust sensor is determined to be a high-speed operation mode, a corresponding control instruction is generated, the dust sensor is controlled to operate in the high-speed operation mode, indoor air circulation is accelerated, and dust detection accuracy is improved.
When the rotating speed of the air conditioner fan is smaller than a preset second rotating speed threshold value, the rotating speed of the air conditioner fan is smaller or even zero, and the noise generated by the air conditioner fan is smaller or even zero, so that the operation mode of the dust sensor is determined to be a low-speed operation mode, a corresponding control instruction is generated, the dust sensor is controlled to operate in the low-speed operation mode, the noise generated by the dust sensor is reduced, and the comfort level of a user in an indoor air conditioning environment is improved.
It is to be understood that the first rotational speed threshold may be greater than the second rotational speed threshold; the first rotational speed threshold may also be equal to the second rotational speed threshold.

Further, after step S24, steps S25 to S28 are also included:
s25, controlling the dust sensor to operate in a high-speed operation mode after receiving an inquiry instruction of a user; the query instruction is used for querying the indoor dust concentration;
s26, controlling the dust sensor to detect and calculate the indoor dust concentration after the dust sensor operates in the high-speed operation mode;
