Problems solved by technology
[0004] However, when using laser sensors, if the light in the storage location of the equipment is always weak or the light is always strong, it will cause problems such as untimely data collection or short service life of the sensor.
Moreover, temporary occlusion will cause the device to switch working status, which is prone to the problem of data collection error

The invention relates to a method and device for controlling a sensor. The method comprises the steps of setting the working mode of the sensor as an interval working mode when equipment starts to operate, and determining the variation amplitude of data collected by the sensor between two discontinuous working; adjusting the working mode of the sensor to a continuous working mode under the situation that the variation amplitude is larger than a preset first threshold value. According to the method and device for controlling the sensor, the stability of an environment is determined according to the data collected by the sensor, so that the sensor enters the continuous working mode to work when the variation amplitude of the environment is large and enters a discontinuous working mode to work when the variation amplitude of the environment is small, the service life of the sensor is guaranteed, and the optimization of the sensitivity of the sensor is guaranteed at the same time.
Description
Technical field [0001] The present disclosure relates to the field of sensor technology, and in particular to a sensor control method and device. Background technique [0002] Air purifier, also known as air cleaner, etc., is a product equipment that can adsorb, decompose or transform various air pollutants, and effectively improve air cleanliness. In an air purifier, a dust sensor used to detect the content of pollutants in the air is its core component. The air purifier controls its own working status according to the data collected by the dust sensor. [0003] Laser sensor is a kind of dust sensor. The laser sensor (also known as the light sensor) can determine the environmental brightness and perform intermittent work after the environmental brightness is lower than a certain value. [0004] However, when using a laser sensor, if the light in the storage location of the device is always weak or the light is always strong, it will cause problems such as delayed data collection o...
