US12587740 - Sensor device and operating method thereof

A sensor device and an operating method thereof are provided. The sensor device includes a microcontroller and a sensor module. The microcontroller performs the operating method. Firstly, the sensor device enters a configuration mode after being activated. The sensor device enters a detection mode after a timeout period. The sensor device is on standby for detecting if any event occurs under the detection mode. When any event is detected, a trigger signal is generated, and the sensor device enters a broadcast mode to broadcast the trigger signal. After another timeout period, the sensor device enters the detection mode again, and is on standby for detecting if the event is restored to a default state. When the event is restored to the default state, the sensor device is reset for detecting if the event occurs.

The patent describes a sensor device that utilizes a microcontroller to manage its operational modes, including configuration, detection, and broadcast modes, based on event detection and timeout periods. The device is designed to reset and re-enter detection mode once an event is restored to a default state, enhancing its functionality in monitoring and responding to specific occurrences.

Claim 1

1 . An operating method of a sensor device, comprising: entering the sensor device into a configuration mode after the sensor device is activated; entering the sensor device into a detection mode after a timeout period, wherein the sensor device is on standby for detecting whether or not an event occurs while in the detection mode; forming a trigger signal when the sensor device detects the event while in the detection mode, and entering the sensor device into a broadcast mode for broadcasting the trigger signal; entering the sensor device into the detection mode after another timeout period, wherein the sensor device is on standby for detecting whether or not the event is restored to a default state while in the detection mode; entering the sensor device into a detection-off mode; and when the event is restored to the default state, switching the sensor device from the detection-off mode to the detection mode. entering the sensor device into a configuration mode after the sensor device is activated; entering the sensor device into a detection mode after a timeout period, wherein the sensor device is on standby for detecting whether or not an event occurs while in the detection mode; forming a trigger signal when the sensor device detects the event while in the detection mode, and entering the sensor device into a broadcast mode for broadcasting the trigger signal; entering the sensor device into the detection mode after another timeout period, wherein the sensor device is on standby for detecting whether or not the event is restored to a default state while in the detection mode; entering the sensor device into a detection-off mode; and when the event is restored to the default state, switching the sensor device from the detection-off mode to the detection mode.
