A sensor assembly for a lecturer auto-tracking system is provided to detect a lecturer correctly by adjusting an angle of an infrared sensor module. A sensor assembly for a lecturer auto-tracking system includes a body(100), and an infrared sensor module(200). The body is buried on a vertical wall plane in a width direction. Holes having the same size are formed at a predetermined height and gap. The infrared sensor module has a light emitting unit(210) and a light receiving unit(220). The light emitting unit divides an infrared illumination plane into at least two illumination planes to prevent diffusion, and illuminates an infrared ray to detect a position of a lecturer. The light receiving unit receives the emitted infrared ray. The infrared sensor module is assembled slantingly to the holes formed on the body.
