Abstract

The invention provides a control method, device, electrical appliance and storage medium of a PM2.5 sensor, and relates to the field of electrical appliances. The control method of the PM2.5 sensor of the present invention includes: controlling the operation of the PM2.5 sensor for a first period of time, and detecting a first PM2.5 concentration value within the first period of time by the PM2.5 sensor; Controlling the PM2.5 sensor to suspend operation and waiting for a second period of time; controlling the PM2.5 sensor to operate again for the first period of time, and detecting the second PM2 within the first period of time through the PM2.5 sensor .5 concentration value; determine the change rate of PM2.5 concentration value according to the first PM2.5 concentration value and the second PM2.5 concentration value; compare the change rate and the calibration change rate, and adjust the said change rate according to the comparison result Second time. The control method, device, electrical appliance and storage medium of the PM2.5 sensor of the present invention determine the change rate of PM2.5 concentration value by comparing the PM2.5 concentration value in two adjacent operation cycles, thereby effectively reducing the light decay phenomenon band The coming PM2.5 sensor life decay problem.

Description

technical field [0001] The present invention relates to the field of electrical appliances, in particular, to a control method, device, electrical appliance and storage medium of a PM2.5 sensor. Background technique [0002] At present, in household appliances, the commonly used PM2.5 sensor detects PM2.5 particle concentration by infrared or laser. Due to the phenomenon of light decay, when the PM2.5 sensor works for a long time, the luminous intensity will decrease due to light decay, while PM2.5. 5 The sensor detects the concentration of PM2.5 particles by detecting the reflected light of PM2.5 particles in the airflow, so the phenomenon of light decay will reduce the measurement accuracy of the PM2.5 sensor, resulting in the attenuation of the service life of the PM2.5 sensor, and it is necessary to replace the PM2 frequently. 5 sensors to ensure measurement accuracy. SUMMARY OF THE INVENTION [0003] The problem solved by the present invention is that the measurement...
