A rotating direction and rotating speed sensing device includes a tested unit, a housing, and a Hall effect sensor disposed in the housing. The tested unit includes an output shaft, and a toothed disk sleeved on and driven by the output shaft. The Hall effect sensor positionally corresponds to the toothed disk for detecting rotating direction and rotating speed, and includes three Hall effect sensing elements spaced apart along a first straight line, and a first pin and a second pin respectively outputting a first signal and a second signal when the toothed disk rotates. The first straight line cooperates with a tangential direction of the toothed disk to form an included angle that ranges in a predetermined angle range, such that a phase shift between the first signal and the second signal ranges from 45 degrees to 135 degrees when the toothed disk rotates.
