[noparse][[/noparse] Program Description ]

---

' This PIR demo allows you to see how to go about allowing a warm-up time
' for the sensor to settle, as well as displayed number of times tripped
' and possibly activating an alarm or relay, in this case the LED.· The LED
' should have a 220 ohm or 330 ohm resistor in series with it.
