PIR MOTION SENSOR
Passive Infrared (PIR) Motion Sensors protect space by 'looking' for
changes in infrared (heat) energy levels caused by
movement of an
intruder. The passive infrared detectors are passive devices. i.e., they
do not transmit any form of energy. When
a person enters and moves within the detecting zone, his body which is
at its normal temperature of 98.6 degree F., radiates
more (or less) thermal energy than the surroundings and such minute
difference in thermal energy is detected by the PIR. In
simple
words, PIR keeps a picture of the heat levels in its view and keeps on
comparing the new view with the stored one. In
case there is any
change then they activate the alarm.
