This work studies the expected signal of dark matter particles in terrestrial detectors. In particular,we focus on the direct detection technique, based on the study of the scattering of dark matter particles by a nucleus in a detector. In the calculation, we have considered the dark matter model, the geographical location of the detector, and the neutrino background for the site. In this work, we have computed the expected detection rate and annual and diurnal modulations concerning the detection of WIMPs. The signal predictions were carried out for experiments that may be performed in the planned new underground facility ANDES (Agua Negra DeepExperimental Site), to be built in San Juan, Argentina. We also consider a response function and an efficiency similar to the Xenon1T detector to get a more realistic signal approximation. There are only two direct dark matter detectors planned to settle in the Southern Hemisphere to this day. Therefore, it is crucial to start modeling the signals and backgrounds to define the characteristics that improve dark matter detection in the ANDES laboratory.
