To avoid false alarms:
Don't mount the PIR sensor in direct sunlight (as PIR detects moving heat sources) or in a place affected by wind. When installing outside, it's best to mount in a shady, protected place with minimal changing temperatures. Also, avoiding mounting on UPVC or metal doorframe surfaces which may reduce transmission range.
