Abstract

The invention discloses a sensor calibration method, a sensor and air treatment equipment. The sensor calibration method comprises the following steps: acquiring a calibration instruction; adjusting emission light intensity of detection light, and acquiring receiving light intensity of light received by a light receiving assembly; when a difference value obtained by subtracting first preset lightintensity by the receiving light intensity is more than or equal to zero, and less than or equal to a first preset difference value, updating standard emission light intensity to the current emissionlight intensity, and updating detection reference light intensity to the current receiving light intensity. The sensor calibration method improves the consistency of sensors.

Description

technical field [0001] The invention relates to the technical field of sensing, in particular to a sensor calibration method, a sensor and air processing equipment. Background technique [0002] In the air treatment equipment, there is usually a filter screen, on the one hand, it can prevent impurities in the indoor air from entering the air treatment equipment and cause equipment failure, and on the other hand, it can also improve the quality of the indoor air. As the use time increases, dust, germs, etc. will adhere to the filter, so it is necessary to test the cleanliness of the filter. The sensor used to detect the cleanliness of the filter includes a light-emitting component and a light-receiving component, which are respectively installed on both sides of the filter. When dust, germs, etc. are attached to the filter, the light intensity received by the light-receiving component will change. In order to realize the detection of the cleanliness of the filter screen. Ho...
