A [`SensorBase`](https://rapi.sleaze.dev/classes/SensorBase.md) that outputs data about the [`AirDensity`](https://rapi.sleaze.dev/classes/AtmosphereSensor.md) and [`RelativeWindVelocity`](https://rapi.sleaze.dev/classes/AtmosphereSensor.md) at the sensor's position.

## Properties

### AirDensity

```luau
AtmosphereSensor.AirDensity: number = 0
```

- Tags: Read only, Read capabilities: Basic, Save only, Simulation access

Measures the density of the air where the sensor is positioned.

### RelativeWindVelocity

```luau
AtmosphereSensor.RelativeWindVelocity: Vector3 = Vector3.zero
```

- Tags: Read only, Read capabilities: Basic, Save only, Simulation access

Reports the wind velocity relative to the sensor.
