Abstract
Methods and systems may include a motion sensor and logic to sample an output signal of the motion sensor. The logic can also be configured to track an amount of time the motion sensor is triggered based on the output signal, and transmit the amount of time over a wireless link on a periodic basis.
Claims22
A method comprising:
- sampling an output signal of a passive infrared motion sensor;
- conducting a repetitive increment of a counter value in response to a first trigger event in the output signal, the first trigger event including a rising edge transition which corresponds to motion detected by the passive infrared motion sensor, and wherein the repetitive increment is conducted in accordance with a clock timer;
- discontinuing the repetitive increment in response to a second trigger event in the output signal, the second trigger event including an expiration of a first idleness period after a falling edge transition, wherein the falling edge transition corresponds to a lack of motion detected by the passive infrared motion sensor;
- adding the counter value to a cumulative value in response to the second trigger event, wherein the cumulative value indicates an amount of time the passive infrared motion sensor is triggered;
- activating a wireless interface;
- transmitting the cumulative value via the wireless interface;
- and
- deactivating the wireless interface in response to receiving an acknowledgement of the transmission of the cumulative value.

A non-transitory computer readable storage medium comprising a set of stored instructions which, if executed by a processor, cause a computer to:
- sample an output signal of a motion sensor;
- conduct a repetitive increment of a counter value in response to a first trigger event in the output signal, the first trigger event corresponding to motion detected by the motion sensor;
- discontinue the repetitive increment in response to a second trigger event in the output signal, the second trigger event corresponding to a lack of motion detected by the motion sensor;
- add the counter value to a cumulative value in response to the second trigger event, wherein the cumulative value indicates an amount of time the motion sensor is triggered;
- and
- transmit the cumulative value over a wireless link on a periodic basis.
