Abstract

A method and device for humidity sensor value compensation and an air quality detector. The method comprises: acquiring a humidity value detected by a humidity sensor, a first temperature value detected by a first temperature sensor, and an actual temperature value detected by the first temperature sensor, and acquiring a second temperature value detected by a second temperature sensor; reading system time and retrieving a humidity compensation coefficient; generating the compensate humidity on the basis of the first temperature value, of the second temperature value, and of the humidity compensation coefficient in a pre-established humidity sensor value compensation model; generating an actual humidity value on the basis of the humidity value and of the compensated humidity; and, displaying the actual humidity value.

Description

technical field [0001] The invention belongs to the technical field of air quality detection, and in particular relates to a numerical compensation method and device for a humidity sensor and an air quality detector. Background technique [0002] With the advent of the era of intelligent air quality detectors, the configuration of air quality detectors is becoming more and more powerful, and the functions are becoming more and more complete. More and more users use air quality detectors to detect air quality. Quality inspection, and display the detected humidity value of the air, so that the user can understand the humidity value of the environment. [0003] However, due to the air humidity value detected by the air quality detector in the prior art, the humidity sensor needs to be placed outside the air quality detector to detect a relatively accurate humidity value. When the humidity sensor is placed inside the air quality detector, It is easily affected by the heat sourc...
