A method for deploying at least one climate sensor in an indoor space includes: several candidate deploy points in the indoor space are obtained. Climate properties at the candidate deploy points are obtained. Deploy-point-number limit is obtained. Available deploy point sets, which conform to the deploy-point-number limit, are generated according to the candidate deploy points. Climate-property differences of the available deploy point sets are calculated according to the climate properties at the candidate deploy points. The climate-property differences of the available deploy point sets are differences between the climate properties at the available deploy point sets and those at the candidate deploy points. A target deploy point set, climate-property difference of which is the least among those of the available deploy point sets, is selected from the available deploy point sets. At least one first climate sensor is deployed at the target deploy point of the target deploy point set.
