FORMALDEHYDE CONCENTRATION MEASUREMENT METHOD AND APPARATUS, AND AIR PURIFIER

摘要

The present disclosure relates to a formaldehyde concentration measurement method and apparatus, and an air purifier. The formaldehyde concentration measurement method includes: determining an initial formaldehyde concentration value measured by a formaldehyde sensor; acquiring temperature information and/or humidity information of an environment surrounding the formaldehyde sensor; determining a formaldehyde concentration compensation value of the formaldehyde sensor according to the temperature information and/or the humidity information; determining a target formaldehyde concentration value of the formaldehyde sensor according to the formaldehyde concentration compensation value and the initial formaldehyde concentration value. According to the formaldehyde concentration measurement method, errors of the formaldehyde concentration value measured by the formaldehyde sensor in different temperature and humidity environments can be reduced, thereby improving the measurement accuracy of the formaldehyde sensor.
