Presence Sensors vs Motion Sensors: Which Do You Need?
QSQuick Sense Team 5 min read
Choosing between motion and presence sensors comes down to one question: do people stay still in the space?
Motion sensors (PIR)
Passive infrared sensors detect changes in heat caused by movement. They're perfect for transit spaces — corridors, staircases, parking, and entrances — where people are always moving.
Presence sensors
Presence sensors detect micro-movements and continuous occupancy. They're ideal for offices, study rooms, and conference rooms where a person may sit still for long stretches.
Quick decision guide
- People passing through → Motion sensor
- People sitting and working → Presence sensor
- Large open area through obstacles → Microwave sensor
