Abstract
Embodiments of the present disclosure relate to methods, sensors, and systems for low power sensing. One method for low power sensing includes receiving a detection signal from a detector of a sensor to a delay flip flop (DFF). The method includes switching a DFF output state in response to a switching of the detection signal, when the DFF is reset, transmitting an event report signal from the DFF to a processor of the sensor when the DFF output state switches, and maintaining the DFF output in a steady state, when the DFF is not reset.
