The operation principleof the motion detection mechanism in the WB-MSW v.3 sensor is as follows. The module constantly receives "raw" values from the ADC to which the motion sensor is connected (register 281). In the absence of movement, these values are virtually unchanged. When moving radiating in the IR range of the object in the field of view of the sensor is a sharp increase and a sharp decline in the values read from the ADC. 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).
