The present disclosure discloses a method for compensating a measured environmental parameter. The method may include obtaining one or more sets of conditions associated with a heat generating device including an electric power value of the heat generating device. The method may further include, for each set of the one or more sets of conditions, obtaining a plurality of groups of measured data acquired by a first sensing device, and a plurality of groups of reference data, which are both associated with an environmental parameter corresponding to a power-on duration of the heat generating device. The method may further include determining, for each group of the plurality of groups of measured data and reference data, a deviation of the environmental parameter associated with the first sensing device between the measured data and the reference data, and determining a relationship between the deviation and the power-on duration of the heat generating device.
