environment according to the Doppler effect principle.
When a person or moving object enters the detection range, KM501S starts to
energize the load. If it remains active while within detection range, the switch will repeat the time delay without de-energizing.
Keeping still or leaving the detection range, the switch will automatically power off after a period of delay.
