Can you use pir sensors for entry and exit?

Yes, PIR (Passive Infrared) sensors can be effectively used for both entry and exit purposes. They detect changes in infrared radiation caused by the movement of people or objects, making them suitable for monitoring doorways or passageways. When placed strategically, they can trigger alarms or notifications when someone enters or exits a designated area. However, it’s important to consider placement to avoid false alarms and ensure optimal detection.
