Description

technical field [0001] The invention belongs to the technical field of air quality detection, and in particular relates to a temperature sensor numerical compensation method, a device 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 detection, and display the temperature value of the detected air, so that the user can understand the temperature value of the environment. [0003] However, due to the temperature value of the air detected by the air quality detector in the prior art, the temperature sensor needs to be placed outside the air quality detector to detect a relatively accurate temperature value. When the temperature sensor is placed inside the air quality detector, It is easily affect...
