Abstract
A system may include a digital sensor system including a sensor element and a digital interface. The digital interface may provide a wake-up signal based on a sensing action being performed by the sensor element after a predefined event is detected by the digital sensor system. The system may include a microcontroller to receive the wake-up signal provided by the digital interface, and wake from a sleep mode based on receiving the wake-up signal provided by the digital interface.
Claims20
A system, comprising:
- a digital sensor system including:
- a sensor element;
- a wakeup circuit to provide a first wakeup signal to the sensor element based on a predefined event being detected,
- the first wakeup signal activating the sensor element for performing a sensing action;
- a digital interface to:
- provide a second wakeup signal based on the sensing action being performed by the sensor element and a result of the sensing action;
- and
- a microcontroller to:
- receive the second wakeup signal provided by the digital interface, and
- wake from a sleep mode based on receiving the second wakeup signal provided by the digital interface.
