Problems solved by technology

[0003] If the sensor needs to work for a long time, the internal fan and laser detection unit will be in a long-term working state. At this time, excessive heat is likely to be generated, which greatly shortens the life of the fan, especially the laser detection unit.
As a result, the life of the entire sensor is greatly shortened
[0004] The sensor works for a long time without interruption and consumes a lot of energy, which is not conducive to power saving
On the other hand, it is unreasonable to rely on the sensor to work for a long time without interruption in order to obtain accurate air state data.

Abstract

The invention discloses an air state monitoring method. The method comprises the steps that S1, a sensor is driven to perform detection during a first time length within a specific working cycle so that detected air state data can be obtained, and the sensor is enabled to stop working to be dormant until the working cycle is completed; S2, the sensor is driven to perform detection during a second time length smaller than the first time length within the specific working cycle so that detected air state data can be obtained; S3, when it is judged that the error range of the air state data obtained through detection this time and the air state data obtained through detection last time does not exceed an error range, S4 is performed; S4, the sensor is enabled to stop working to be dormant until the working cycle is completed, and then S2 continues to be performed.

Description

technical field [0001] The invention relates to the technical field of air detection, in particular to an air state monitoring method and an air state monitoring device for realizing the monitoring method. Background technique [0002] Haze weather has a great impact on human health, especially PM2.5. The current air purification equipment and air quality monitoring equipment will use sensors to monitor the particles in the air to measure the concentration of the corresponding particles in the air to judge the air quality, and use the content of PM2.5 as an important reference index . For PM2.5 (even for other particles) monitoring sensors, the basic working principle is as follows: the sensor has a fan to let the air flow, and the sensor is also equipped with a laser detection unit, which can monitor the number of tiny particles passing through the flowing air per unit time , to determine the concentration of dust. [0003] If the sensor needs to work for a long time, it...
