Quick Start Guide : Pyroelectric Infrared Sensor
Every objects emit IR(=Infra-Red) ray in
respond to its temperature.
Pyroelectric Infrared Sensor detects "change"
of IR distribution within its sensing area.
* sensing area is determined by lens design.
Amplifier and comparator circuits on evaluation
board amplifies
sensor’s output signal and
generate digital High/Low signal. (Next page)
(Please make sure lens is attached on board.)
