Abstract: An alarm triggering method for a sensor and an electronic device using the same are proposed. The method is applicable to an electronic device and includes the following steps. A sensor signal is received from the sensor. Whether a signal magnitude of the sensor signal satisfies a first triggering condition associated with a first determination threshold is determined. In response to the signal magnitude satisfying the first triggering condition, whether the signal magnitude satisfies a second triggering condition associated with a second determination threshold or a third triggering condition associated with a time determination threshold is further determined, where the second determination threshold is greater than the first determination threshold. When the signal magnitude satisfies the second triggering condition or the third triggering condition, the sensor is determined to be in an alarm state so as to output an alarm signal.
