Abstract
The direction sensing apparatus according to the present invention comprises a sensing circuit, a computing module, and a judging unit. The sensing circuit detects the gravity direction of an object and produces at least a detecting signal. The computing module receives the detecting signal, and produces at least a computing value according to at least a threshold value and the detecting signal. The judging unit receives the computing value, and gives a state of gravity direction of the object according to the computing value. Thereby, the present invention shrinks the area of circuits and hence saving cost by means of the simple circuit structure of the computing module.
