### Sensor

Occuspace sensors collect signal activity data. Every sensor has an associated ID on the back, which you will use during installation.

### Sensor Placement

A sensor placement refers to where a sensor is placed within a zone. This is mapped to a physical location, usually denoted by a label like "1A" on marked-up floorplans.
