The present invention relates to a method for detecting a rotation speed and a rotation direction of a rotating apparatus with the digital detection of a single sensor. In the method, a turnable which is connected with a rotation axis with a same axial center is provided on the rotating apparatus. Different directions of the circumference of the turnable are provided with a plurality of inducing pieces of a same sensor. The position angles formed by adjacent inducing pieces are not equal. The inducing pieces are arranged in the sequence of the magnitude of the position angle. When the turnable rotates, a sensor detects the pulse output generated by the inducing pieces. The pulse signal is obtained through a shaping circuit and is outputted to an arithmetic circuit and is connected to a display circuit. A time period S for rotating the turnable for a circle is the summation of a plurality of adjacent pulse interval lengths of a plurality of inducing piece compositions. The rotation speed of the turnable is digitally displayed. The arrival sequence of spacing interval of random adjacent pulse is obtained for determining that the rotation direction of the turnable is clockwise direction or counter-clockwise direction. The invention requires only one sensor for completing the digital detection to the rotation speed and rotation direction of the rotating apparatus. The installation position of the inducing piece of the sensor has no high requirement and the structure is simple. The cost for digital detection and the cost for installing the sensor are reduced.
