Embedded road icing sensor

The invention relates to an embedded road icing sensor, which comprises a shell, a capacitance plate, a circuit board and a battery. A cavity used for containing the battery and the circuit board is formed in the shell; the circuit board and the battery are both connected with the inner wall of the cavity; the capacitance plate is connected with the upper surface of the shell and electrically connected with the circuit board; and the circuit board is electrically connected with the battery. The sensor is embedded in a road and detects the icing condition of the road through the capacitance plate mounted at the top; and the embedded road icing sensor is simple in structure, easy and convenient to mount and high in detection sensitivity. 本发明涉及种埋入式道路结冰传感器，包括壳体、电容极板、电路板和电池，所述壳体的内部具有用于容纳所述电池和所述电路板的腔体，所述电路板和所述电池均与所述腔体的内壁相连接，所述电容极板与所述壳体的上表面相连接，所述电容极板与所述电路板电连接，所述电路板与所述电池电连接。本发明的传感器埋设在道路内，通过安装在顶部的电容极板检测道路结冰状况。本发明结构简单、安装简便、检测灵敏度高。
