The present invention discloses a temperature automatic adjustment method in a conference room. The method comprises the following steps: S1, obtaining the starting time T0 of a target conference room; S2, calibrating the suitable temperature value W0 of the target conference room, and obtaining the temperature value W in the target conference room; and S3, adjusting the brightness of the target conference room based on the T0, and adjusting of the temperature in the target conference room based on the relation of the W0 and the W. The temperature automatic adjustment method in the conference room makes the time point for adjusting and controlling the temperature in the conference room in advance through obtaining of the starting time of the conference room, the temperature automatic adjustment method in conference room firstly adjusts the brightness in the conference room at the time point to prevent the external light and an external environment from causing influence on the temperature adjusting effect, compares the actual temperature in the conference room with the suitable temperature to obtain a comparison result, and makes a targeted temperature adjusting and control scheme according to the comparison result. The temperature automatic adjustment method in the conference room realizes the automatic adjusting of the temperature in the conference room so as to improve the effect of the temperature automatic adjustment.
