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)

While there's no IR distribution
change, AOUT is 1.65V and COUT
is HIGH(=3.3V). When it detects
that, AOUT varies and once AOUT
crosses threshold, COUT falls to
LOW(=0V).
In the sample code, we detect this
COUT change with GPIO external
interruption and IRQ handler sets a
flag which is periodically monitored
in main loop.(Next page)
