This paper proposes a new automatic calibration method for the sensor networks which measure the distribution of physical fields, such as in-room thermal temperature fields. In case of measuring the distribution of room's temperature, the regular calibration of the sensors is necessary for obtaining reliable information. However, it is not an easy task in the case of a large scale sensor network, because the manual calibration in such a system is time consuming and costly. To solve the problem, this present study proposes the new method which is based on the two concepts of regression analysis and cross validation. The new method is explained and the efficient extensions are also proposed, and the performance of the proposed methods is verified by experiments and simulations.
