Changes in raw values immediately increase the value of '''Current motion''' (the current average of the intensity of movement), which then begins to slowly subside for a few seconds. Each new sharp change in the value received from the ADC, again "charges" the register '''Current motion'''. '''Max Motion''' in the register is recorded on the maximum value of the Current register of motion in the last N seconds (N is the width of the time window over which is calculated the maximum value recorded in the storage register 282). | Changes in raw values immediately increase the value of '''Current motion''' (the current average of the intensity of movement), which then begins to slowly subside for a few seconds.

The device template contains two parameters: '''Current motion''' and '''Max Motion'''. If the motion sensor is polled quickly (several times per second), we can use the '''Current motion''' parameter to detect motion with good time resolution. If the sensor is rarely polled (for example, every 30 seconds, in a large network), then we can skip the rapid single movement of the object: in this case, we should use the value '''Max Motion''' and set the width of the time window for calculating the maximum ''number'' of motion is obviously greater than the sensor polling period. | |||
