# sensor

A collision filter for an entity that collides with everything.

```
static let sensor: CollisionFilter
```

## Discussion

The sensor collision filter is typically used by rays in ray casts,
shapes in convex shape casts, and trigger volumes. It corresponds to a
[`group`](/documentation/RealityKit/CollisionFilter/group) and [`mask`](/documentation/RealityKit/CollisionFilter/mask) both set to
[`all`](/documentation/RealityKit/CollisionGroup/all).
