  We present an analysis on the sensitivity to the active-sterile neutrino
mixing with Germanium (Ge) and Silicon (Si) detectors in the context of the
proposed coherent elastic neutrino-nucleus experiment in India. The study has
been carried out with 3 (active) $+$ 1 (sterile) neutrino oscillation model. It
is observed that the measurements that can be carried out with the Ge detector
exhibit better sensitivity to the active-sterile neutrino mixing as compared to
the Si detector. Both detectors are able to exclude most of the anomaly regions
observed by the GALLIUM experiment. The Ge detector with mass 10 kg, can
observe the active-sterile neutrino oscillation at 95$\%$ confidence level,
provided that $\sin^{2}2\theta_{14}\geq 0.09$ at $\Delta m^{2}_{41}$ = 1.0
eV$^{2}$ for an exposure of 1-yr. At higher values of $\Delta m^{2}_{41}$, a
better sensitivity is obtained at a short baseline. It is also found that the
threshold as well as resolution of the detectors play a crucial role on the
measurements of active-sterile neutrino mixing parameters.
