The invention relates to a rain and fog sensor, laminated glass and an automobile. The rain and fog sensor comprises a capacitance digital conversion circuit, a switch array and an FPC board. At least three mutually-insulated rainfall detection electrodes are arranged on the front face of the FPC board, at least two independent mutually-insulated fog quantity detection electrodes are arranged on the back face of the FPC board, and the coverage area of the rainfall detection electrodes is larger than that of the fog quantity detection electrodes. Each fog quantity detection electrode is covered by the normal projection of the rainfall detection electrode on the FPC board; each rainfall detection electrode is electrically connected with the capacitance digital conversion circuit and the ground through a switch array in a time-sharing gating manner, and each fog quantity detection electrode is electrically connected with the capacitance digital conversion circuit.
