A tread detecting device and a trend detecting module are provided. The tread detecting device is disposed at a first predetermined thickness of a tire. The tread detecting device includes a control module providing a voltage or a current, and a tread detection module including a first tread detecting layer. The first tread detecting layer is disposed at the first predetermined thickness of the tire. The control module is electrically connected to the tread detecting module. The control module detects a variation of an impedance value of the tread detecting module to determine whether the thickness of the tread of the tire is less than or equal to the first predetermined thickness.
