The weak mixing angle is a fundamental parameter of the electroweak theory in the Standard Model (SM), and its measurement in the low energy region is still not precisely determined. Different probes, such as the atomic parity violation, coherent elastic neutrino-nucleus scattering (CEνNS), and parity-violating electron scattering on different nuclei, are sensitive to the weak mixing angle value. After the measurement of CEνNS by the COHERENT experiment, other experiments are also expected to confirm the observation. Such measurements will allow to put stronger constraints or discover new physics as well as to probe the SM by measuring its parameters. In this work, the weak mixing angle at low energies, which can be measured with increased precision in future results of CEνNS experiments is discussed. In addition to providing a comprehensive test of the electroweak theory at the quantum loop level, such measurements serve to study new physics interactions beyond the SM at the TeV scale and beyond.
