Disclosure is related to an electromagnetic wave sensing apparatus with integration of multiple sensors, and a method for applying the apparatus. According to one of the embodiments, the method adapted to an electronic wave sensing apparatus includes an initialized step of a host enabled to configure one or more sensors of the electronic wave sensing apparatus. The initialization for those sensors includes one or more setting items selected from resolution, gain, data rate, frequency, and driving current. A next step is to set up a control unit electrically connected with the multiple sensors, and the related setting items are such as output format, output gain, output source, output level, and output driving current. Based on the setting items, the signals will be shaped accordingly and be output. In response to the setting items, the control unit drives one or more internal devices or external devices to function the various applications.

A method of interrupt control for a control unit of an electronic system includes receiving digital data; determining a value of the digital data; and sending interrupt signals to a host by the following methods according to the value: when the control unit is in a second signal sending status and after the value of the digital data increases to be greater than a first threshold and remains greater than the first threshold for a first period of time, switching the control unit to a first signal sending status; and when the control unit is in the first signal sending status and after the value of the digital data decreases to be smaller than a second threshold and remains smaller than the second threshold for a second period of time, switching the control unit to the second signal sending status. The second threshold is smaller than the first threshold.
