As shown in the figure, it isa sensing automatically lightmade by newHN911L pyroelectric infrared detection module. The HN911L integrates high - sensitivity infrared sensors, PIR , amplifiers, signal processing circuit andoutput circuit. Itisable to remote sense the faint infrared signals from human motion. The lights can be turned on when people move around, turned off automaticallydelay tens of seconds when people leave.
