PIR false trigger


my concept use parallax pir sensor trigger arduino 328 pro mini 5v. seems work fine other false triggering can once minute or so.

the code written there minute of warm time pir sensor occurs in setup. led triggers whenever pir high, squirt gun can trigger after ten seconds has elapsed since last time triggered , pir high. electronic noise triggers pir?

in order stop false triggers, worth trying of these?
1. pull down resistor on pir pin?
2. low pass filter?
3. decoupling on pir pin?

i thought opinion before tore apart

it's simple circuit, , wouldn't expect noise, unless, line pior processor quite long.  first attempt pulldown resistor on pirpin.

reorpt when solve problem, may else.

good luck,
