description The invention relates to the field of geotechnical science and technology research, in particular to an automatic configuration device and method for moisture content of granite residual soil. Putting the granite residual soil which is basically air-dried into a tray, putting the tray into a closed container, and carrying out initial weight weighing M; a ventilation valve is opened, a heating function is started to evaporate moisture in the soil, and when the humidity obtained by a humidity sensor is smaller than the indoor humidity and is stable, the weight M0 of the completely-dried granite residual soil is read; closing a ventilation valve and a heating function, carrying out atomized water spraying according to the configured water content, increasing the water content by 1-3% each time, and carrying out multiple times of spraying at an interval of 10-20 minutes; when the total weight of the residual soil and water in the disc reaches the preset water content W0, namely Mw/M0 = W0, spraying is stopped, an
