Abstract

The invention discloses a testing method for a sensor, the sensor and air treatment equipment. The testing method for the sensor comprises the following steps: acquiring first receiving optical intensity received by an optical receiving component when an optical transmitting component is closed; acquiring second receiving optical intensity received by the optical receiving component when the optical transmitting component transmits detection light at first transmitting optical intensity; comparing the first receiving optical intensity, the second receiving optical intensity, a first preset threshold and a second preset threshold; when the second receiving optical intensity is greater than the first preset threshold and smaller than the second preset threshold, and the difference between the second receiving optical intensity and the first receiving optical intensity is greater than a first preset difference, confirming the sensor to be normal, and otherwise, confirming the sensor to beabnormal, wherein the first preset threshold is smaller than the second preset threshold. According to the technical scheme provided by the invention, the maintenance efficiency of the sensor is improved.

Description

technical field [0001] The invention relates to the technical field of sensing, in particular to a sensor inspection 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 filter cleanliness. Due to factors such a...
